Engine crash

#1

Hi there!

I have encountered a totally unexpected engine crash… during a main scene switch, probably a collectionProxy loading. I am not able to reproduce this and that scene switch has been tested for months… Could you please try to get some information out of the crash file I attach?

Thanks for your great support!

Do you use any native extension dependencies?

It doesn’t really tell us much. Has it happened again? It crashed on macOS right?

The callstack looks plausible.
Did you get any log from the engine?

Looking at the function + line number that’s being called, it has to do with profile scopes.
Could it be we run out of scopes in some manner?

How do you trigger it?
It there something component type or something you have a large amount of?

Thanks for your help!

  1. macOs with Catalina on a macbook air
  2. it has not happened again
  3. no log in the console
  4. strange thing: the app window stayed open, but totally black

I don’t think we are running out of the game project limits.
