Short description of error

Crash when changing to UV Editor

Exact steps for others to reproduce the error

Click on the "UV Editing" tab

It might be related to having the GPU SubD enabled in preferences, looking at the crash log. In this case I have a file which has a SubD and displace, with the SubD first in the stack (not last) as shown (or it might be the USD system). Click on the UV Editing tab and crash.

Crash log with the stack trace included

Yes I can confirm that with turning off the GPU SubD in preferences the crash doesn't occur.

I cannot reproduce this with either the latest stable or current development versions of Blender:

Please try the latest daily build: https://builder.blender.org/download/

Operating system: macOS-12.2-arm64-arm-64bit 64 Bits
Graphics card: Apple M1 Apple 4.1 Metal - 76.3

I can confirm that switching to UV edit results in a crash in this file. @mano-wii, maybe GPU subdivision is disabled on you card for some reason.

Thanks for checking @kevindietrich - it's consistent and I've seen it with other files too, I've been puzzling as to why this wasn't reproduced.

Oh - I can see the likely problem, @mano-wii is on a Mac. Those machines are so different from PC's and Linux that they aren't always the best bug verification platforms.
