Problem with installing Jitsi

Hey guys,

I have a very strange problem with my Jitsi client.

When I install jisti, I can’t make any general settings. The tab for this is always the same as the tab clicked before.
I uploaded a picture, I hope you can see it.

this problem only occurs on one computer in the company.
I have already tried all the obvious solutions.
Windows restarted, Jitsi reinstalled, etc. Nothing leads to the desired result.

Micrphone and audio settings are also not available.

I am using Windows 10 Pro, version 1903.
Operating system build 18362.476

You need more information, let me know.
Thank you
tom
