Transporter app issue (Can't authorize your user at this time.)

I have this issue with Transporter.
when i am trying to log in to my developer account in Transporter, i am getting this message:

Transporter app issue (Can't authorize your user at this time.)
This action cannot be completed at this time (-22411).

This problem occurred in Mac Os Big Sur & xcode 12.
I'm experiencing the same problem... It's ridiculous how Apple can't make things work!
I also encountered the same problem
still same error for me.
Seriously, what is going on here. This is half-baked. I have the same issue. Anyone have a fix?
