System Information
Operating system: Linux-5.11.0-22-generic-x86_64-with-glibc2.31 64 Bits
Graphics card: NVIDIA GeForce GTX 1080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 465.19.01

Blender Version
Broken: version: 3.0.0 Alpha, branch: master, commit date: 2021-06-26 21:49, hash: 7223a0348f
Worked: 3558bb8eae

Short description of error
Blender either instantly crashes, crashes during "Initialization" or just stalls as soon as I start a preview render with a certain kind of geometry (very weird and hard to describe).
I noticed that some blend files that worked perfectly some days ago now crash Blender. I could boil it down to a single object (that I had to garble a bit because it's from a production file but the result is the same).
I also recompiled some older versions of Blender and could narrow it down to 5f9677fe0c to be the first version that shows the problem.

Exact steps for others to reproduce the error

Download and open the blend file:
Autosmooth_Crash_v02.blend
Start a preview rendering.
Blender either crashes or stalls. Sometimes it takes a while for the crash to happen. Just switch to solid mode and start another preview rendering afterwards.
Reopen Blender and the scene file.
Now delete one of the two UV sets -> Everything renders fine
Alternatively:
Uncheck the Autosmooth option -> Everything renders fine

... very weird.

This is probably related to: #89455

@SteffenD , think the report is duplicate of #89455 (Crash when using Cycles preview or render - custom data layer / auto smooth) (as Rahul said)

@PratikPB2123 Yes, this might be true. Sadly I can't confirm this at the moment as I'm far away from a computer that can run Blender (typing this on a Raspberry Pi) ;)
I'll keep an eye on that issue and add my comments ASAP.

Yep, this really looks the same as #89455 (Crash when using Cycles preview or render - custom data layer / auto smooth), will merge these reports
