Maybe they have back-ported some of this code, into the current Windows 10 September 2019 Updates, and the current versions of KeePass do not like this. Microsoft has been drastically changing the code for virtual desktops in the Insider Releases lately, for example adding features like being able to give names to desktops and such. I think this has to do with how KeePass switches to another virtual desktop during this process. KeePass is basically crashing the current user's session, in a way, unless there is a better way of recovering from this that I do not know about. Pressing CTRL+ALT+DEL and logging-off/rebooting seems like the only way to recover from this.

Pressing CTRL+SHIFT+WINDOWS KEY+B also does not recover from this nor does using CTRL+WINDOWS KEYS+ARROW KEYS (to switch virtual desktops). 2.6.4 - Here I can't select the database in Google Drive. 2.4.3 - There I can open the database but writing new entries does not work. apt-get install) 2.6.4 Snap installation.

If I save a new password in Ubuntu, the entry disappears again after closing and opening KeePass XC.

I have tried it with versions 2.42.1 and 2.43 of KeePass.
