Graphics card: NVIDIA GeForce GTX 1070 Ti/PCIe/SSE2 4.5.0 NVIDIA 496.76

Blender Version
Broken: version: 3.1.2, branch: master, commit date: 2022-03-31 17:40, hash: cc66d1020c3b
Worked: (newest version of Blender that worked as expected)

Short description of error
Freezes when using the Box Hide feature in a particular sculpture

Exact steps for others to reproduce the error
My sculpture had "strings" on it that connect one body part to another.
I tried to remove the stings by using the box hide feature but it always freezes after doing so.
I tried the box hide feature on many other parts and it worked well. It freezes particularly when
box hiding "stringy" parts of a sculpture. I was able to reproduce the same problem many times.

I tried it on my Mac Air M1 and yielded the same results.
i started with a sphere and snake hooked something really thin.
resolution is at 0.004 (hand no problems remeshing even in a lot higher resolutions than this).
Used the box trim and it freezes.

Can confirm it taking long on some "boxes" / "strokes".
This can also happen on UNDO (even if the original "box" / "stroke" was fine.
For me, it was tricky though to find an angle/spot where this happens and then again using the same angle/spot was fast the next try.

Also note this is never a complete freeze for me (it just takes quite long), but blender was always recovering.

@Stephen_Sensei : could you also share the other file (maybe it is a bit easier to reproduce on that one), preferably in the correct state / viewing angle and with a hint on where to drag the box

Hello all,
Sorry. I should have said "Box trim", not box hide.
Box hide and unhide works smoothly in my windows PC and Mac Air m1.
It is the Box Trim that makes it freeze.

Yeah, Box Trim uses exact booleans under the hood, this is known to be slow on hires meshes (and also eat RAM like chocolate).
This has been reported before though, will merge with #84229 (Sculpt Trim tools are very slow)
