Windows 10: How can I stop Windows 11 from crashing and crashing other programs on my computer?

I have Microsoft Windows version 23H2 installed and ever since Windows has updated it it crashes nonstop and I cannot open any of my programs for more than three min before they crash. I have cleanded my disk. Gottenrid of temporary files. Deleted any extra apps that I have only to recieve the message my C drive is full to the max which is not true at all. How do I fix these problems? I have YouTubed for the past 4 hours and tried absolutley everything. I am a designer and cannot use any of my programs. HELP!!

Firefox crashes non-stop!!!

Suggest any methods to stop Firefox from crashing. It crashes right after starting, no more than a second or 3..

Any cache, plugins, antivirus things that might cause it? It is very, very annoying...

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
