Cannot lauch after logging out

OS: Fedora Silverblue

Protonmail Bridge launched fine after booting up the system. However, it failed to launch after logging out from the session. It gave me the following error:

[dadstick@fedora ~]$ flatpak run ch.protonmail.protonmail-bridge
QApplication: invalid style override 'kvantum' passed, ignoring it.

I'll have to reboot the system to fix it. Is there any workaround or would you be able to fix it? Thank you!

Edit: it seems to be a Flatpak specific issue, as I didn't encounter the issue with the rpm version.

Delete the file /var/home/dadstick/.var/app/ch.protonmail.protonmail-bridge/cache/protonmail/bridge-v3/bridge-v3-gui.lock, this seems to be an issue on Proton's side

Thanks for the reply. The issue didn't happen when using the rpm version so it might be a Flatpak specific issue.

[A6GibKm]

it only happens when the app is closed in a bad way. No idea if it happens outside of flatpak, but it is an issue upstream as the file is created properly inside the sandbox.

[sith-on-mars]

I normally wouldn't close the app before I logged out, which I didn't expect to be considered as 'app closed in a bad way'.

[A6GibKm]

The app deletes the file while it is shutting down, clearly something stopped the app from deleting it.

This can happen for example when ones kills the process or uses ctrl+c when running in the terminal. I personally think it is a bad idea on their end as it is super easy to break.

Tried bringing it up in the proton-bridge github, issue got immediately closed claiming it was a flatpak issue.
