2022 Fileserver timeout with Veracrypt container

Question

Hi,
We have changed our 2019 Fileserver to a 2022 server.
Now we are facing a timeout issue here.
On a share is a veracrypt container located.
If I open this on my Win10 20H2 Notebook, open a file from the container and work on different things, after ~10 min I will get a timeout error in Veracrypt, that the connection was closed.
I'm not be able to save the open document from the container after that, even if I reopen the container.
Seems to be some kind of 'feature' on a 2022 server, because the same thing worked good under 2019 and 2016 file servers

Any ideas here?

Cheers
Florian
