[Bug]: Unable to create bottle on fresh install

Describe the bug

On a freshly installed Bottles (without any prior configuration), I am unable to create a new bottle, no matter the environment.

After creating the bottle for the first time in the stable branch, I can create bottles afterwards.

To Reproduce

Get rid ~/.var/app/com.usebottles.bottles, if it exists
Install Bottles flatpak from the latest commit
Launch, set it up and create a bottle

Package

Flatpak from GitHub Artifacts

Distribution

Fedora 37 Silverblue
