[2019] $LoginError_GameCodeFailure [3:0:7]

Just tried to move some stuff from 1 Character to another. The first time it went all good, moved like 100 lbs of Ammo to my mule. Now i wanted to transfer some armor pieces nobody wants to the mule. Stored everything as usual, logged out and tried to rejoin with my mule. Game crashed. Now i get this Error. Searched the Internet and this Subreddit, but haven’t found anything. Any Ideas? I‘m on XB1
