1st startup/login works, subsequent startup fails (Kubuntu / snap)

I have installed Bitwarden 2023.10.0 on Kubuntu 23.10 through snap:

snap install bitwarden

The first startup and login is successful, and I can use Bitwarden as expected.

After closing Bitwarden I can unfortunately no longer open it again. It basically just terminates after a second or two. There is no error message displayed when I try opening it in the console.

Purging and reinstalling Bitwarden yields same result (1st startup/login works, subsequent startup fails).

Any idea how I can debug this?
