UE5 Crashes when changing Map

Development Programming & Scripting

Hi, UE5 crashes when changing to any level,
First line of error:
Assertion failed: ConstantSubsystemProperties.Num() == MutableSubsystemProperties.Num() [File:D:\build++UE5\Sync\Engine\Source\Runtime\Engine\Private\Animation\AnimBlueprintGeneratedClass.cpp] [Line: 391]

I’ve tried:

  • Removing Binaries, Intermediate & Saved folders & regenerate vs files
  • Building project from source
  • Creating new project (no such problem)

Were you able to find any solution?
I am experiencing continuous crashes with that same error line.

Thanks in advance

Hi, sorry for answering late.
I updated to 5.1 but no luck. The problem is on my project and never found it on other projects at all.
