Error creating a file in MetaHuman Creator Unreal Engine 5.6

When I created a character in MetaHuman Creator in Unreal Engine 5.6 itself, I want to create a rig and upload it to content browsers, as described in the video and documentation.

The problem is that when I click on the “Create Full Rig” button, I load up to 75% (it reaches 75 as soon as it appears) and stops at this value, then something happens and the download disappears and the error “character is not rigged” pops up. Please help me solve this problem, there is little information on this subject on the Internet.

I was able to solve the problem as follows, I logged out of Epic Games in the browser and in the app itself, I logged out of FAB and out of Qixel Bridge. I restarted the computer and then logged back in and it helped, in general, the problem is that there is no synchronization with accounts.
