Problem after upgrading project from 4.19 to 4.20

This problem has been now persisting for quite a while and I have no idea what is causing it.

Basically, I made a copy of my 4.19.2 project for 4.20.1 and everytime I try to load it the engine crashes.
On the error log, it is saying that there’s an error in file AsyncLoading.cpp and stuff…
It’s weird because the loading still goes all the way to 95% or 96%.

If you want to see the full error log just ask me.

Thanks,

u should include the log without anyone to ask u, its not secret :smiley:

there is many reason for that, My best advice to u, when u upgrade ur project do the following

  • Backup ur project “just as u did”
  • Delete Build folder
  • Delete Binary folder
  • Intermidaite and saved folders
  • Double click on ur project and let it recompile .

It should work without any confilect, since ur project will only hold ur classes and assets and ur project settings .

Hope this work for u.

Nope, it crashed at the exact same point

edit : I just noticed the error log says something about level streaming, did you know if this was modified in 4.20?
