Short description of error
started blender and turned to eevee shading and it freezes. nothing can click anymore.
found out its because my saved startup file didnt have material on default cube what causes it. so i deleted startup.blend file in config folder and started and eevee shading works again.
i think its bug because what if people dont want have material on default cube on startup file

Steps to Reproduce

  • Open attached file
  • Switch to material preview or render view

Thanks for the report.

I followed your steps and changed the startup file. I did not see any freeze with the new startup file after switching to viewport rendering
Can you confirm the issue with the file I've attached? Do you still have your old startup file? Can you upload that?

I can reproduce this:

  • Open the 2D Animation template
  • Go to object mode and add a mesh, e.g. Monkey
  • Blender freezes

The issue seems to be in rB9c82c00b32802a88b71c22929e9660f7ba4023a8. There is a while loop with a sleep that keeps looping forever.
