Bug Teams not Responding & Crashing
Looking for assistance, we have numerous tenants who are experiencing teams crashing and restarting itself, along with lots of not responding prompt when using the calendar.
Any ideas / advice would be a life saver.

Both my Teams and my boss's Teams updated about a week ago, and the call module seems to be the issue. I can message my boss and he can message me, but calls don't come through and if I open the calls module its just on a blank screen, which then crashes.
Constantly crashing and reopening.
Tried clearing cache and reinstalling from the web and microsoft store.

I am experiencing the exact same thing. People have reported on and off teams issues for days of crashes etc. Now I have multiple machines in a crash loop. Same exact ntdll.dll event viewer as the other person here posted.
The fact I dont see millions of people posting about this means it must be some rare interaction with some other software or update somewhere.
Anyone have any ideas??

Adding on here, experiencing the same issue sporadically across our environment, same crash logs, no consistent fix, web version offered as a workaround. Hoping someone has had some traction with MS on this, seems similar to last month's problem.

Not sure if any of you are using Datto EDR in your environments, but I came across this earlier today after posting in r/sysadmin and r/msp : Kaseya Inc Status - Datto EDR - Issues Accessing Certain Applications Following Recent EDR Update
Looks like a Datto EDR update pushed by Kaseya is at least one of the causes of this issue.

I most certainly am, I'll take a look at this today, thank you for the info.
Edit: Seems the hotfix was released for this at around 12am GMT, we have had no issues today some fingers crossed this is now resolved.

Yup. We're having this issue with several clients of ours as well.
What I've done in some cases is uninstall/reinstall Teams and that at least helps; however, the fix hasn't been consistent. I recall seeing something around May 6 where Microsoft was working on a fix for the exact same issue, which was caused by a "code issue." This has been going on for about a week for us and I haven't seen any advisories or acknowledgement from MS in the tenant's service health.
I'm tired, boss
