Installing flatpak apps from flathub.org

it seems to be x11 only, no wayland. at least when looking into your permissions output

also why you install it with no --user ?

@coderus sorry my fault, forgot --user. Redone it with --user but error at the end is same. I think @rinigus is right. This App has problems with display (Wayland). Too bad, I hoped to correct the low audio volume (DAC, Bluetooth) with this app. Thank you for the answers.
