"No working capture handler found for your system."

[Fleafa]

What happened?

It has been a while since I used Plasma (CachyOS as I installed it), but I'm sure it was working there. Using Niri (installed alongside Plasma), NormCap quits due to errors.

How did you install NormCap?

FlatPak (Linux)

Operating System + Version?

CachyOS (installed as Plasma version)

[Linux only] Display Server (DS) + Desktop environment (DE)?

Wayland + Niri

Debug log output?*
