User defined keyboard shortcut not wirking any more

Hi,
after upgrading RDM from 2025.3.30 to 2026.1.14 my user defined shortcut for copying a password to the clipboard, Ctrl-Q, is not working any more.
Changing it to some other Ctrl shortcut did not help.
The predefined CTRL-Shift-B is also not working, though it is shown in the context menu:
The context menu itself works.

Thanks in advance.
