Didn't test, but this is probably caused by
68586d2c18.Changed status from 'Needs Triage' to: 'Needs User Info'
@SimonThommes I tested your file, but it does not show a mesh and just reports missing linked files. Also your screenshots do not give me enough information on the setting of the solidify modifier. Can you repair the file so I can test?
Added subscriber: @PratikPB2123
Oh sorry, I missed making the mesh local. I replaced the file

Raising the priority since this is a very recent regression.
@HDMaster84 , can you check?
Ok I found one critical mistake in my code where I accidentally swapped two letters. Just fixing that didn't make it look good for this model yet. After tweaking a few of the new epsilon values introduced in the mentioned patch to handle weird cases I got a much better result. Changing those values did also not mess up my other tests.
@SimonThommes You are very welcome to test the patch that I will put up in a few minutes and if something is still unstable for no reason, please share the file. Choosing good thresholds for all cases is an asymptotic process.
@HDMaster84 I tested the patch. It makes an improvement, but it does not seem to fully fix the issue. In the initial example I shared there is still a (smaller)artefact visible that wasn't there before.
I also tested another mesh where it appears to be a regression.
I will update the example file in the task description to include both meshes.

Tagging high priority bugs with 3.1 so we get an overview of the work remaining for that release. If the module owner does not consider this planned for 3.1, please change the tag to 3.2 or lower the priority to normal.
The commit that caused this is only in 3.2, not 3.1, so I think we can use that tag instead.
