I can confirm same issue. with recent 2.83.6 build (As I reported) (LTS version not crash)
https://developer.blender.org/T80287

I supposed if it only happen with some Nvidia video cards, but it seems not.
I may close my report, if it is confirmed by developer, as duplicate.

If need to send movie which reploduce it, I already made, so ask me please. (but I think quite a few user easy reproduce this crash with current 2.83.6

Btw if I start scene without any mesh, then change layout as UV editing, (start from empty scene), crash not happen.
Then I load mesh , activate go to edit-mode to check UV blender crash.

I haven't refreshed page before merging. I can reproduce crash in 2.91 following these steps:

  • New General template
  • Go to UV Editing workspace
  • Toggle to object mode
  • Save File
  • Open file
  • Go to Sculpting > UV Editing > Sculpting workspace
    Blender crashes

First I got similar backtrace to what @lichtwerk posted. But it looks that it is quite random. So I am not quite sure if it's same issue as reported here or if it is even same issue as reported in #80287.

There was a mistake applying the fix to 2.83-LTS as this bug doesn't exist in master, see 79945c8126 for detail (fix attached).

I ran into some bugs in master relating to switching workspaces that look closer to the backtrace from @iss, although they don't involve edit-mode, so I'll open a new report for that.
