Linux Mint 21.3 with Elgato USB cam: "Could not play camera stream" while it works everywhere else. ¯\_(ツ)_/¯
It is a simple camera app, it only does the basics, no extra features (v. 47.1). Btw, Flatpak version works fine on my laptop with LMDE 6.
Dittoing Maybe_Matty. I get a frozen loading spiral when I try and boot it. Running Linux Mint 21.3 Cinnamon.
