Interesting. I've never seen this one before. Thanks for including the output log! That's super helpful.
I'll preface everything else by saying that I'm not sure if this can be fixed, and I'd be happy to issue a refund if you're not interested in debugging (or if debugging steps fail).
This appears to be a rare Unity issue that affects a ton of games on specific machines (it seems to be correlated with AMD processors, but there's not a whole lot of information beyond developers complaining about it on the Unity forums). So far, it seems like the following things can resolve it:
Running on a different machine if there's one available (the issue appears to only happen with very specific system builds, and a different machine will probably be fine).
Update your graphics drivers and BIOS.
Make sure you have enough memory (I recommend at least 4GB. Closing other programs might help with that too).
Check your hard drive for SMART errors, and, if you're using it for swap space, try using a different one.
The best solution, updating the engine version, is unfortunately not an option because I'm using a bunch of packages that won't survive. I tried pulling the character library into a more recent version of Unity for my next game and it broke in some truly terrifying ways.
