Notes:

• The crash happens on a newly created project, too
• If you try to reopen the project after the crash, it will crash while opening
• Tested with Alienware M15 R4, i9-10980HK CPU @ 2.40GHz, 32 GB RAM, RTX 3080
• Possibly hardware dependent, so far been able to reproduce only with devices having Intel CPUs and RTX 30XX GPUs
• Crash is still reproducible after installing Blender 4.0 on the system
