Messenger crashes as soon as launched

I have this problem too! When Messenger would not work after the startup of Windows 11 or even after starting it manually. In my case, the Messenger app never stops "Getting Started" loading, so I don't know if it would work for other cases. My solution is manually killing Microsoft Edge in Task Manager (msedge.exe). Sometimes, I have to end the task the msedgewebview2.exe until the Messenger stops spinning. (For me, msedgewebview2.exe would always come back. So I have to spam end tasks to all of them until it works.)

I discovered this issue when I tried using RPCS3 when having Microsoft Edge on. The app would work properly if I ran the RPCS3 app without Edge on or after immediately exiting Edge. (Chrome also caused this, in my case.)

PS. Ending the task of msedgewebview2.exe does not endanger any of my apps because it would grow back up like Hydra, and I never understand why.
