Clipboard issue: Host - Debian 11, VM - Debian 12

[CatJump]

After some regular update, I was faced with the fact that the clipboard began to fall off with the following error on the VM:

It only helps to manually terminate the process "VBoxClient --clipboard" and then run it. After that, the clipboard works again for a while and after a while the error repeats. Does anyone have any ideas about the causes of this problem?

I tried reinstalling VirtualBox - the problem remained.
