thanks for the report. I tried to replicate this locally but unable to catch the issue.
here is the .blend file I've made
#100571.blend

So in uploaded .blend you get mesh object without subdivisions applied in edit mode?

found. it seems to depend on the position of the modifiers in the stack. if you put the armature modifier after the subdivision modifier, the error will become reproducible in your file (I also had to enable the on cage option, although in my file it seems to have broken without it)

In this case it looks expected, but in the case shown in the video, the result doesn't look expected.
We need a simplified .blend file to be able to replicate the problem.

Thanks for the file, but I cannot reproduce this with either the latest stable or current development versions of Blender:

Please try the latest daily build: https://builder.blender.org/download/

Go to File → Defaults → Load Factory Settings and then load your file to see if you still can reproduce this issue.

Also check if this is related to GPU Subdivision. {nav Edit > Preferences... > Viewport > Subdivision > GPU Subdivision}

If the problem persists, please give us more clear instructions on how to reproduce it from scratch.

resetting the settings helped. but the problem is that I don't want to reset the settings: I have my own theme, keyboard layout, etc. I have everything customized for me. is there any suggestion which option can cause this behavior (it's not GPU subdivision, I checked, there is no difference)?

@sanek2005 hi, could you upload userprefs.blend file then? (C:\Users\user_name\AppData\Roaming\Blender Foundation\Blender\3.2\config\)

I can confirm the problem.
It was apparently introduced in bf8a26b745.
modifiers_disable_subsurf_temporary function used to calculate crasy space, does not correctly re-enable subsurf.
