My team's app occasionally displays an error, preventing me from opening it and attending meetings.Please give me a solution to this.Error is attached below.

I also have the same problem cross two different Windows 10 devices.

Similar issue in my Teams. (with Win11 24H2)

Teams works well in the beginning.
I can start an audio call or a meeting with others.
But after I finished the audio call or the meeting and I want to start another one. I get:

We've run into an issueOpps, something went wrong![UnknownError][Error:Cannot read properties of undefined (reading 'baseimageUrl')]Slot name:UNKNOWNSession ID:...Date and time stamp

In Teams, I get

We run into an issueTry again in a few minutes

Teams is not crashing, but it is no longer usable.
I cannot switch to other contacts. I stuck in the current scree. Chatting with the current contact still works.
And I see incoming calls, but I when I accept, the connections ends.

I already tried to delete all "Unkown Users" from my chats (because of the Slot name: UNKNOWN in the error message), but it didn't help.
Also reinstalling Teams did not solve the problem.

I'm also getting the same problem. In addition, when receiving error " We've run into an issue", I noticed that none of the menu options on the side panel are working at all.

Exact same issue. If it happens when in a discussion, able to still type in chat and receive messages but not able to switch to any other chat or tab from the side panel, open settings or anything else, if I try to open a chat in a new window it opens a page that displays the error. Web teams is perfectly fine in the mean time

I'm also getting the same problem. In addition, when receiving error " We've run into an issue", I noticed that none of the menu options on the side panel are working at all.

I have done everything you suggest, but the problem persists.
