I recommend contacting your IT administrator and ask him/her to monitor incident TM1462874in the Microsoft 365 admin center > Service Health for the latest updates, as Microsoft is actively working on a resolution. Once the service has been fully restored, please update Teams to the latest version and restart the application if needed.
Also, as many members of the community may not yet be aware of this incident, I hope you find this information helpful. Sharing or highlighting this response can help bring greater visibility to the issue, making it easier for others who are experiencing similar challenges to find relevant information and support.
Thank you for your patience and understanding. I wish you a wonderful day ahead.
