Unreal Engine 4.23.1 stuck at 18%

Hi,

I have an iMac 2021 with the M1 chip.
16Go RAM

Suddenly my Unreal Engine 4.23.1 stopped working and he’s now stuck at 18%.

I really don’t know what happened and I tried a lot of things like :

  • Completely reinstall Epic Games Launcher & UE 4.23.1
  • Uncomment some lines in the ConsoleVariables.ini (r.ShaderDevelopmentMode=1 and r.XGEShaderCompile = 0)

When the process is stuck at 18%, there is ShaderCompiler working in my monitor like :

Is this normal that these ShaderCompileWorker are taking all my processor ? Then the UE4 Editor throw an error and it finish.

Would be very cool to have some help on that because I really don’t know how to fix that.

Thanks in advance !
