MS Teams keeps randomly crashing

Everytime i m in a call it crashes - goes to a black screen then i have to force restart the pc. This only happens on Teams calls is there anyway to stop it - its driving me bananas? 

Hi Danny IOP,


Thank you for the posting in our forum community.


Regarding your description, kindly try to clearing the Teams cache to see if it helps via following steps.


1.    Fully exit the Microsoft Teams desktop client. To do this, either right click Teams from the Icon Tray and select ‘Quit’, or run Task Manager and fully kill the process.


2.    Go to File Explorer, and type in %appdata%\Microsoft\teams


3.    Once in the directory, you’ll see a few of the following folders:


-         From ‘Application Cache’, go to Cache and delete any of the files in the Cache location. “%appdata%\Microsoft\teams\application cache\cache”


-         From ‘Blob_storage’, delete any files that are located in here if any. “%appdata%\Microsoft\teams\blob_storage”


-         Within ‘Cache’, delete all files “%appdata%\Microsoft\teams\Cache”


-         Within ‘databases’, delete all files “%appdata%\Microsoft\teams\databases”


-         Within ‘GPUCache’, delete all files “%appdata%\Microsoft\teams\GPUcache”


-         Within ‘IndexedDB’, delete the .db file “%appdata%\Microsoft\teams\IndexedDB”


-         Within ‘Local Storage’, delete all files “%appdata%\Microsoft\teams\Local Storage”


-         Lastly, from ‘tmp’, delete any file “%appdata%\Microsoft\teams\tmp”


Once finally done clearing, you can now restart Teams from your local desktop and check if the issue disappears.


Also, for further analysis I need to collect below information from you.


1.          Does this issue is also happened in MS Teams web client?


2.          Could you please provide us detailed version of MS Teams desktop client?

3.          Could you please provide us detailed video about this issue via private message for further analysis?
