I've been happily playing skyfactory 3 for weeks. Tonight I tried starting the mod pack using the FTB launcher (like I always do, nothing new), and got a message saying it could not update, validate, or find my profile.
I've removed the account from FTB and re-added it. Each time I try to log in to my MS account using the question mark icon in the bottom left of the FTB app, the login says successful, but when I try to launch the game, it says it doesn't know who I am.
I haven't found a solution, but at least one other person is having the same experience - https://github.com/FTBTeam/FTB-App/issues/709
