I don’t use Battle.net but I had a similar issue when using EA Desktop through Lutris. The program would demand a restart to apply updates then would just shutdown and say the same thing next time you ran it, if it even still ran.
My permanent fix was to use Bottles for EA Games and it’s worked fine ever since then. Lutris works fine for everything else though.
I’m older GenZ “Zillennial”?
What in particular makes you think there’s not many of us on here? Not like Lemmy makes you state your age on your account.
