Most of those are simple warnings regarding deprecated field, which is fine 
The typeError at the bottom might be what’s going wrong, and it looks to be related to a failing migration.
My recommendation is to Launch the game in Safe Configuration and let it migrate game data (pf2e has the Troubleshooting option as well, where you can re-migrate world entities to try and fix bugs, so I recommend giving that a run-through in Safe Config with all modules disabled).
After the re-migration, try to confirm whether you’re hitting the problem. Hopefully your world data will be good and functional. If you aren’t hitting the problem, you can enable your modules again. If you run into the problem after re-enabling them, it might still be a module at fault, in which case we’ll need to either enable the modules a few at a time, or check for red errors in the console which might point to the one that’s leading to that typeError.
