Operating system / Graphics card
Win 10 64-Bit / RX 5700xt

Blender Version
Broken: 2.93.1
Worked: N/A (Have only been using blender since 2.93)

Short description of error
Render Engine: Cycles
(Rendered Viewport) Increasing subsurface value in Material properties on an object causes computer to hang.
(Rendering Image) When trying to render an image (with the previous information) no image will be rendered and AMD Bug report tab will appear.

Exact steps for others to reproduce the error
On an object, go to the material properties pane, add a material and change the "Subsurface" value to anything along the scale. Only occurs during rendered viewport or trying to render an image.

Test File:
Donut.blend

Can not reproduce with the default startup file. Does this happen with specific file?

Can you please attach the simple .blend file?

Some extra Information: Just did a little bit of testing on the start up and found that when I added SSS to the default cube it did not cause a crash. Moved it above origin, still no crash. But then as soon as I added a plane beneath it caused the same crash. Hope this can help.

Thank you for the file. Still no crash here. Does this happen with both GPU and CPU device?

Still steps to recreate the crash are unclear to me. Can you please mention the exact steps? or a short video will also be useful

Also, please attach the crash logs: https://docs.blender.org/manual/en/latest/troubleshooting/crash.html#windows

Thanks for the video. May be the issue is with your GPU. Does the issue start happening after recent changes in Driver settings or updates?

Can you check again after upgrading the driver to the recent version: https://docs.blender.org/manual/en/latest/troubleshooting/gpu/windows/amd.html

Please attach the system info generated from Help menu: Open Blender -> Help -> Save System Info).

Also, I can not reproduce on my system
System Information

Graphics card : AMD Radeon(TM) 535 ATI Technologies .```

So I found a way to get the SSS to work again without causing graphics to break. I re-installed an older version of Radeon Software (21.5.2).

I also tried the optional build of the driver (21.7.1).

I've added my System-Info here incase you still would like to take a look at it.

Thanks for checking. Can I consider the issue is fixed at your end?

Some new findings. Re-updated to most recent version of AMD Software and found that Branched path tracing also caused the problem. Once changed to standard path tracing issue no longer occured.

@BuffaloMozzarella , can you please create a separate report for it?

Separate report is useful I guess if steps are different to recreate the crash.

Also add crash logs in the new report: https://docs.blender.org/manual/en/latest/troubleshooting/crash.html

I went through the steps to try and find a crash log but can not find it anywhere, I think it causes a hang but doesn't actually crash blender.

Will make a seperate Report for it though. Do I just post and set as resolved?

Just report the issue. Triagers, developers will check the report and decide the status :)
