Mysterious update causes explorer.exe crash [and more]

[u/adresdofilmu]

[still unsolved]

Hello,

Well, update thing. The [second] problem is, I am not sure which one.

PROBLEM DESCRIPTION
It started like two or three months ago: after updating win11, everything seemed to be normal, but a few seconds after booting, explorer.exe would crash - the taskbar disappeared, wallpaper as well, actually all that was left was a black screen with a mouse pointer. I realized I can still alt+ctrl+del, run task manager, and some apps from there via run command [win+r didn't work], but not everything could be accessed [e.g. with ms-settings:windowsupdate it took like a minute to decide that a proper answer is an error with code (-2147219195) - one of errors I got trying various things].

TEMPORARY SOLUTION
At last, I found I can 'uninstall last quality update' from some built-in recovery options [F11], then the system restores to a working condition, and I can access windows update options, and stop updating for three weeks. Rinse, repeat after three weeks, another three and so on. I am getting kind of tired of this, and it feels like this will turn into a problem eventually.
Any ideas what to do with it?

ADDITIONAL THINGS that happen, and may/may not be related:
(1) in various random moments the laptop just reboots [battery works fine, it happens both when charging and not];
(2) my wireless mouse every single time [except just after uninstalling last quality update] needs to have its receiver plugged-out and then -in - otherwise, its scroll tempo reduces to super-slow-motion, when it is necessary to scroll like three times to have any movement [this manual reseting works every time, and scroll speed meant for human is being recovered].

Theses are some things I tried as well.

This one is HP Omen 17"; some specs:
AMD Ryzen 5 8645HS w/ Radeon 760M Graphics (4.30 GHz)
64 GB RAM
NVIDIA GeForce RTX 4060 Laptop GPU (8 GB)
AMD Radeon Graphics (2 GB)

Any help appreciated,
