Philipp Oeser (lichtwerk) changed the status of T86308: Crash to desktop on Boolean union exact operation from Needs Triage to Confirmed.

Yeah, it is caused by rBa3f091d7ceda: Change Exact Boolean modifier to skip round trip through BMesh.

Okay, I just tried appending my models into a new blend file and it works. All my objects got imported correctly and the problem with the modifiers is now gone. God bless the "Append" function!

Can confirm that increasing INSTANCED_PANEL_UNIQUE_STR_LEN to 5 (as @Vincent Blankfield (vvv) proposed) solves the issue.
Not familiar with the code though, @Hans Goudey (HooglyBoogly) : mind checking?

Anthony Edlin (krash) added a comment to T47129: new Bmesh boolean is deleting some of edges data, (Creases and Bweigh).

Note that now that the new "Exact" mode doesn't go through bmesh it preserves the data. Updated patch to compile on recent version in case anyone still wants bmesh boolean to also work.

Philipp Oeser (lichtwerk) added a comment to T86267: Remesh modifier prevents UV modifiers from working.

Ah wait, since the solution is to let the UV Project modifier create a new UVMap if preceeding modifier destroys it, it is indeed the same issue as T59376: UV project modifier not working after modifiers that dont provide a UVMap (e.g skin, remesh) and I will merge these reports.

Falk David (filedescriptor) closed T86236: Boolean modifier performance issues as Invalid.

Since 2.91 Blender has a new solver for booleans called Exact. This solver can solve trickier cases but is also slower. The old method is still available as the Fast solver. Read more here: https://wiki.blender.org/wiki/Reference/Release_Notes/2.91/Modeling#Boolean.

Dmitry (PRAYTHEPO) added a comment to T86236: Boolean modifier performance issues.

One thing to mention: to replicate this performance bug you need to create scene with boolean individually for each version of blender. If you create boolean scene in 2.83.12 and then open in 2.9x, it works fine. But boolean operation created in 2.9x works bad and laggy by itself and imported to 2.83.12 it also works ugly

Jagannadhan Ravi (easythrees) updated the diff for D10609: [Request for collaboration] Attempt at multithreading deformation in simple modifiers.

Crash fixed (I think), though this approach is understandably very slow. I wonder if it makes more sense to split the work into chunks and do it that way.
