Thank you for sharing the logs and PowerShell. Got out the following:

20:11:45 -- error -- SSO: ssoerr - SSO failed. ErrorCode: Error Desc: Status: caa10001
Look fun: "...talk to your IT admin.." 😄
But the error leads to the following page:
https://support.microsoft.com/en-us/help/4041047/modern-authentication-fails-in-teams-status-code-4c7
But I'm not sure how this is different with Room System and Teams desktop client. With the desktop client we have not faced this issue.
Edit: This was because of conditional access and licences, it is working now \o/
