So, follow up. I've tried everything, compatibility mode, locking out the e cores, nothing will get the launcher up. So, it is not the OS, e-cores, 12th gen is just breaking the launcher, NOW I totally understand that you guys are biting the bullet trying to get an expansion out, but I can't play the expansion at this point when it arrives, sad face Subscriber. =( Try to keep us up to date on the status of this issue please, have a lovely holiday.
