Program crashes when drag'n'dropping more than one file

[kedge26]

Switcheroo Crashes every time I try to drag and drop more than 1 picture (in my case: HEIC images) at once.
Opening multiple files with the open-button works fine. Drag and drop also works, but only if I drop one file at a time.

Affected Version: 2.2.0, installed as Flatpak via Flathub on Ubuntu 24.04.
Issue is reproducible on multiple different systems.

Any suggestions?
