I'm having the same issue, I can't seem to login to my Bethesda account. I even have GOG Galaxy installed and opened. any ideas on what to do here? i really wanna play online with my friends.

Im not even able to create Bethesda account for my GOG copy, but my Steam version works well. I always end with this error when enter my email into ingame account creation:

Kex Assertion Failed:
0 && "Invalid configuration for GetBNetExternalAuthForSignInToken"

And then I instantly got other error, something like

ERROR_FORMAT_NOT_SUPPORTED
File: C:\|Jenkins\Workspace\blablafile Line 368

What Betheda support telling for this?

even with the new patch they still haven't fixed this yet, do i really have to wait another 14 days? fuck microshit
