Bitwarden Desktop App not Starting (Ubuntu)

Hello there,
It’s been a few days since I was able to start the Bitwarden desktop app on Ubuntu 25.10.
I have installed the app on the snap store (App Center) and there are no updates available.
This is the output of the bitwarden command:

$ bitwarden

I don’t remember touching some settings or anything, is this my fault somehow? How can I fix this?
Thanks for the help.

Try to delete the local data of the desktop app – and after that log in again.
