What happened?

If shared clipboard is enabled, I can't use explorer's file copy/paste function: pressing copy on files/folders does nothing, no paste option is available anywhere. If I disable shared clipboard (no need to reboot guest), then copy/paste starts working. Enabling shared clipbard again breaks copy function again.

How can we reproduce this?

Enable bidirectional shared clipboard, open windows file explorer, select a file and press copy on it. Then try to paste it somewhere where you have writing permissions - paste option is not available, like nothing was copied. Now disable shared clipboard from guest window main menu and try to copy/paste again - works properly now.
