This is not a malfunctioning hardware thing. I faced the same issue for a few days on silverblue, where my 2 year old zen3 laptop would slow down to a crawl and eventually the gnome-shell would freeze. Somehow it resolved itself somewhere between kernel and gnome-shell + mutter updates
Hey are you still facing this issue. I also faced this twice on fedora 41 silverblue but it seems to have resolved itself after some updates
