Audio (speakers and micro) not working on windows

Hello

the sound doesn't work on the zoom app on windows 10.
It worked before this summer...
Is this due to an update?
In the meantime I have also added external speakers to my system but the problem remains even when I remove them.

Note that the speaker and microphone work with other software and also with the Web version of Zoom.

I did different tests and I also uninstalled and reinstalled zoom but the problem remains.

Can you help me, please?
