i was playing around with the '09 client, installing extra stuff (polygamy, plus! 5.02). then i logged in on mercury messenger on android 12 (VERY bad idea, ik), and tried to log out on the PC, then it just crashed and won't open again. i already uninstalled all extras and even all the data i could find in appdata local and roaming. it doesn't work. i am using Reunion7 as the PC OS, and the phone i tried to log into with mercury is a redmi 9i.

here's the footage (.avi download bc filegarden is stupid).
