simular here on an Intel HD Graphics 530 (GT2) Gen 9 (Gnome, X11), mostly a immediate freeze during web browsing. 
CRTL+F3 and dmesg shows what's up.
note:
I'm mostly running lastest homebrewed vanilla kernels (with GPU firmware loaded), currently 5.11. 
so I guess you will see this with fedora kernel 5.11 too (if not somehow patched away), cause this GPU hangs have a history. 
IMO, they were completely away around 5.9 (?) and came back with 5.10.x (?)
moons ago I tested with/without GPU FW on Fedora kernels: no differences

anyway, I'll test what @ED Greshko suggested.
