Details of my setup: Hardware: Thinkpad T14-Gen 2, AMD Ryzen 7 Pro graphics, 16G Ram. Software (currently): freshly installed Ubuntu 22.04.3LTS, Gnome 42.9.
Problem description: I've been using Ubuntu (single boot) on my current machine flawlessly for 1 month. 4 days ago, I installed Wine on my computer and also did a Kernel upgrade, either of these two completely messed up the computer (I'd bet for the second). Firefox, Thunderbird, Nautilus, Terminal freezes in about 1-5 minute of use, then in 10 second the screen as well, then in 5 seconds everything. If I don't open any of these, eg. use Chrome for browsing, the computer lasts a bit longer, but still freezes in at most 15 minutes.
My attempts: The problem occurs both on Xorg and Wayland. I tried updating my drivers. I tried to install several Ubuntu versions (23.04, 22.04,20.04) and run them with multiple kernels. None of these solved the problem. I ran memteset and it gave no error. When running in recovery mode, the above-mentioned applications still crash in 5-15 minutes intervals, but the system does not. In the log files, I see the following things reoccurring (see below): Window manager warning: Overwriting existing binding of keysym 38 , Failed to load module "canberra-gtk-module" , gnome-shell crashed with sigsegv, GNOME Shell crashed with signal 11.
Question: How can I identify whether the problem is related to kernel or hardware or something else?
For further details regarding log files see below.

Disclaimer: I am not an Linux expert, but I've been using Ubuntu for about 7 years now and I was able to sort all my problems with the helpful questions I see on askUbunutu and some limited programming experience. I know that there are many questions of this sort already on askUbunut, but I tried to follow up on them with no success. (See here, here, here and here and probably uncountably more)
