Symptoms

when i try to start a match sometimes, when it takes too long to find a match, it opens the loading screen and gets stuck there, with it eventually showing the text "something's not quite right" beneath the board in the loading screen. when i close the game and restart it doesn't affect my rating so i assume this happens only with AI.
i haven't have this happen to me with practice mode only on rated matches, but i may have just been lucky as i haven't played practice a lot.

i haven't encountered this bug when playing in proton 6.3-8

Reproduction

use proton 7.0-1 or experimental, then unlock rated play and then try to play, eventually you will get stuck on the load screen, there isn't anything which makes you certain to get this bug, but it isn't uncommon, once i tried to play and got stuck on the loading screen 5 times in a row. so i assume it isn't random, i just don't know what causes it.
