Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?

Blender Version
Broken: version: 3.0.0 Alpha, branch: master, commit date: 2021-08-06 02:10, hash:

Worked: (newest version of Blender that worked as expected)
Short description of error
When trying to cut away polygons with delete, crash.
When trying to recalculate Normals on Faces in Alt-N menu selection, crash.
I was able to duplicate out some Faces from area I needed to trim up, then separated and no crash occurred, but crashed again when trying to reset/recalculte normals.
Very simple part, 4 rectangles, flat, I had cut a smaller rectangle out of their centers as they were too big. Nothing difficult. This was happening a few days ago. I am going to revert back to Aug 4th for now, will wait for Alpha for Aug 7th or 8th.
Exact steps for others to reproduce the error
4 long strip polygons. Cut them with knife to shorten them. Use Ring tool to cut a dual line through them longitudinally. You have now created thin inner rectangles in the core of the strips. Try to delete the outer rectangles from them, leaving the inner cores. Blender should then crash. Also if you try to recalculate the faces (Alt-N/Recalculate Normals) of left-overs after the cut (as they get odd shadows on them), then it should also crash.
[Based on the default startup or an attached .blend file (as simple as possible)]

I think I'm running into the same issue. I'll attach a small test file and some crash logs, which are from the newest Cycles-X daily build, hash
499008939a48
(Merge branch 'master' into cycles-x).It crashes not only with face specific operations, but also when trying to dissolve a vertex or edge, or connect vertices with

Can reproduce crash with the file provided by @Snudl.
Recent regression it seems. Will bisect to find the culprit.
(Though unsure about the steps to recreate the crash from scratch which Bill has mentioned but will confirm for now since the crash does not happen with little old builds)
All crashes caused by {647a8bff06bfabeafa01333d4b9d8d8b8ae1c569}
May be I should report each of them separately.
Could not reproduce the crash with debug build. @Snudl, @lionheart001 can you please mention the exact steps to reproduce the mesh.
I could not reproduce this from scratch with present described steps.
(I fear to confirm the report in present state. May be other triagers, developers will check the issue to confirm it)

Changed status from 'Needs Triage' to: 'Archived'
Closing, since this report is too vague includes multiple reports in one, also, it seems likely these issues are a duplicate of #90256 which has been resolved.
Please test a recent build of the
master
branch, if you are still running into these problems open a new reports with the exact steps to redo the bug.Sorry if I complicated the issue, though it would have been nice to have some time to respond here. Anyway, since I can still reproduce this on master, here's my new report: https://developer.blender.org/T90532
