I have a few users experiencing issues with the Micollab 7.3, these users are running either 1809 or 1903 Windows 10 versions. When there is an incoming call the popup to answer the call just vanishes, they will still hear the call ringing with no way to answer it. The other issue, is where the call will just drop randomly and they will see a Micollab error popup named "Micollab Client Problem Reporting", see attached screenshot for that. I did some troubleshooting by checking logs and though I had nailed it down to .NET as the cause. I tried reinstalling .NET, Micollab, tried different user profiles, uninstalled some .NET updates, nothing seems to fix the issue. There is a Windows error log in Mitel folder that contained the following:

I did think I had it nailed down to .NET, but I tried all the available fixes to no avail. Has anyone experienced this with Micollab 7.3? Any help here is much appreciated.
We seem to be having the exact same issue with our 7.3 users also. Gone down the route of reinstalling .net, running DISM repair, ensuring both Windows Updates & Dell Updates are fully upto date but still seeing random crashes from a handful of users. Did you get any further with this issue? Did you report to Mitel?
Below is a snap shot of the error we see in event viewer - we are running MiCollab 7.3.0.402
