Windows 11: fail-fast error and missing PC in main console

[alfredo]

Hi,
I have a problem in a network of windows 11 machines. I installed the latest of veyon 4.9.0 and I get the following error when the master console is opened and is sharing the screen:

veyon-worker.exe fail-fast: Exception handlers will not be called and the process will be terminated.

The applications continues to run, but I have to close the window with the error many times.
Moreover, there is a second malfunction that I started to notice with windows 11, I do not know the exact version of veyon: sometimes some PCs are not visibile in the master console, but if I close and reopen it, I can see all PCs again.
Thank you

P.S. let me know if you need logs files.
