How many mods did you install all at once? Does the base game with NO mods work? If your game was working before which mods did you install after that? Best way to troubleshoot is to see if the base game works. Then install utility mods like SKSE, engine fixes, ect and recheck. If things are still good try adding a few at a time plus any requirements for them (read the mod's web page carefully) and rechecking. Don't forget to check LOOT after each set. Keep going a few mods at a time. Adding 50 mods all at once, you can expect problems and no idea which mod caused it.

Why does anyone WANT "achievements"? Never understood the point of this feature.

Have you tried playing with the load order? Try moving a sign mod before or after Norther Roads and see if that fixes the problem.

That log is showing a lot of dll files. Remove them all from your Skyrim directory to a temp folder so the game is pure vanilla. Also disable ALL your mods. Does the game work? Put in just one very small texture mod. Does it still crash? I am almost certain it is an incompatible dll mod that is the problem. It usually is.

Instead of trying to figure out crash logs I would recommend first checking the game with no mods at all (eliminating all the non-vanilla Dlls as well). Then with just SKSE, engine fixes and other utility mods making sure they are all for your current Skyrim version. Then adding mods starting with those that are requirements for many other mods, a few at a time. Trying to narrow down a problem with hundreds of mods enabled would be difficult. I prefer an elimination (or rather an addition) method. Since the crash occurs at character creation you won't need to play for a long time to see if your crash problem is gone. Never could figure out crash logs gibberish.

I agree, I hate how they pop up every time you fast travel instead of staying where you left them or going back to where they were first found instead of where you meant them to stay. I make it a point to never get on any horse because of that. With the exception of Arvak or a summonable daedric mount. So nice to have them where and when you want them and then have them conveniently vanish when no longer needed. But mostly I've found no real need of any horse to ride I just like collecting them if only I could get them to stay where I tried to put them. I tried filling the corral near Whiterun but it didn't work out They all simply wouldn't stay there.

You could simply get the list of mods in the collection and install only the mods with lower requirements. It doesn't really take that long even for a list of hundreds. Also a lot of graphic mods come in several versions 1K, 2K or 4K. Installing by yourself you can pick the lower version which might play better on your computer. Also looking at the individual mods in the collection you might not want everything in their list. Or choose a collection that has lower requirements.

Does it happen with no mods installed? When does it happen? When the game loads or at some other time? If it happens without any mods try verifying your files from Steam. If the vanilla game is fine, uninstall all your mods then starting with the utility mods like Engine Fixes and SKSE try installing a few at a time until you localize the problem.

When you say the area outside the cell isn't there does that mean you chose the option "escape my cell" and after you opened the door and tried to walk out of the cell you fell into the void or does it mean that from within the cell the outside area was there but only appeared as a grey void? The last option might mean that is a room bounds issue and some mod placed improperly linked room bounds between the two areas. The mod "More informative console" might help finding the problem. Or use XEdit to find any mods affecting that cell. Have you tried the "camping in the woods" option or one of the other options and is the problem still there? You could try an elimination process by disabling most of your modlist except Live Another Life and its requirements and see if the problem persists. Tedious but it can narrow down the problem area. In the creation kit you can place room bounds around two adjacent areas of a cell, placed so that they are flush with each other. Once you do so from in one room bound looking into the other all you will see is a grey void. To fix that a portal must be created in the CK and placed against the interface and sized to just fit a doorway and then linked to each room bound. Then you will be able to see through that door/portal to the other room. A mod that improperly tried to optimize that cell might be at fault. On the other hand if you step out of the cell and start falling into the void some mod actually deleted or disabled part of the building outside the cell. Good luck finding the culprit.

If you walk on the grey area do you fall through into the void or is it just visual? Could it be a room bound issue if it is just visual?

Why use Wabbajack at all? It's for installing collections of mods, right? Find all the individual mods in the collection and download and install each individually using Loot after installing each mod to check for missing requirements.

You must sort MO2's left panel by "Priority", since if you try to sort by any of the other columns you can't move the mods around

I have the 1.6.1170 version of Skyrim and the CC pack. If you download the cc pack, it shouldn't affect any mods that are already for that version of the exe.

If you get the mod Campfire you will be able to buy or make backpacks. Campfire - Complete Camping System at Skyrim Nexus - Mods and Community

Making mods is fun. To start with for the basics watch this tutorial series from Bethesda. The tutorial is a dungeon but the principle is the same. For adding a merchant Darkfox127 has a good tutorial. To make it buyable you will need to make a npc to sell the house and place him somewhere in the world then add a custom dialog to him. Something like you ask him if the house if for sale. He says "Yes, $10,000 Septims. Do you want it?" Then speech options show: 1 Don't have enough money, 2. Not now, 3 Yes, I'll take it. If option 3 money is removed from your inventory and a key is added. Fairly simple but that is the basics of buying a house. You can also use a quest (other than the dialog which is it's own quest).
