We’ve had a few people with Teams troubles similar to what you describe.  Interestingly all on Windows 10, but I’m not sure that’s a meaningful datapoint or not.

Reinstalling from scratch has gotten all of them running again:

It sometimes takes a couple of Teams starts to get back up and running.  Teams appears to have some sort of “self-healing” routines that it runs.

Subject: Teams error

A user said his Teams “died” and won’t let him log in and gives the following error: /adfs/services/trust/13/windowstransport

He tried a reboot and that didn’t change anything. Any ideas?

Thank you,
