Pressing Winkey to open the start menu and then clicking on the app (Anki) isn't doing anything. But strangely enough, I'm having no issues opening it from the software manager. I believe it has to do with the command used in the start menu's shortcut, since if I try to copy paste on the terminal I get this:
/usr/bin/flatpak run --branch=test --arch=x86_64 --command=anki --file-forwarding net.ankiweb.Anki @@ %f @@
erro: Falha ao abrir “/home/vinicius/%f”
Error opening that path.
