Closing a session sometimes locks encrypted user directory

[Choppel]

Bug Description

We are using RustDesk on multiple Linux Mint clients with the user directory encrypted. Starting and running a session between these PCs works fine. But when one of the clients terminates the connection (by closing the RustDesk window) sometimes one or both PCs start to act weird. All open programs show various error messages that they cannot access files etc. If the user tries to access their home directory it seems that it's not mounted anymore.

How to Reproduce

Install Linux Mint on 2 PCs with the home directory encrypted (not full disk encryption).
Install RustDesk on both PCs and start a session between them both.
Open some apps like firefox and nemo. Close the connection on one of the clients by closing the RustDesk window (not via "disconnect" button).
Check if the apps are still working. Sometimes they don't because the home directory is not mounted anymore.
If it does not happen on the first try, try multiple times.

Expected Behavior

The mounted encrypted home directory should not crash.

Operating system(s) on local side and remote side

Although I don't know why this obvious bug was changed into a discussion, the bug seems to only happen when using the home encryption of Linux Mint. I reinstalled my PC some weeks ago with full encryption and the bug did not occur.
