crashinfo output

i was using my pc as usual when i suddenly noticed that the system has froze,
after which it proceeded to reboot and autoran savecore and crashinfo and
generated a coredump and text file containing an analysis of the coredump,
after i quick looked through the analysis of the coredump it seems telegram
desktop is at responsible, which might be related to drm-kmod?(crashinfo output
attached)

i still have the coredump, in case i help in any way, although i have to
mention that i haven't been to reproduce this panic again as of yet, also, my
hardware is fine as well, to rule out the possibility of bad hardware, sorry
for the report in the case this report is useless
