I have tried playing this on both Windows 11 and EndeavorOS, and while its perfectly stable offline on my linux side; no issues in CPU battles, training mode, story, couch 1v1s. When I go online, the first match against someone is perfectly stable, but if I rematch them in the standard BO3 format, the game will disconnect around 20 seconds into the second match routinely. I have seen this in both online casual, online ranked, and custom lobbies with friends and strangers alike, but the second I switch to Windows I can play 10 games in a row against the same person without issue.
