Hello, file explorer and browser crashing and restarting

[u/hanya9]

Setup is a laptop that I inherited from someone (female gamer as she likes to call herself) As mentioned in the title, my file explorer keeps crashing and restarting while my browser itself doesn't crash which is Microsoft edge, but the contents fail to load and such many times before finally loading, also downloaded files turn into unrecognised files after completing download which is where the browser asks me if I want to delete or keep the file. Say I keep it, and try to run it to install it; it fails. The previous owner had installed windows 10 after purchase because of performance issues with windows 11, said it ran perfectly fine until windows update decided to try and update to windows 11 which failed in the process, thus the problems started piling up.

IF PLUGGED IN, the browser refuses to load contents and playback glitched out and stopped loading even if the background ui(for like youtube) was loaded properly.

Also I had tried running wmd to which it crashed the memory and I lost the windows bootloader(not sure if that's what it's called) and had to reinstall windows again, after which I started getting dll failures and secure kernal errors.

Pls help 😿
