Same problem here. Cameras work and records video, but Kamoso is just a black screen. Pictures are visible for a fraction of a second after they taken as they are shrunken from the main screen area down to the bottom right during the save animation. VLC is able to show video from both capture devices (/dev/video0 and /dev/video1), so it's definitely a Kamoso (or Qt5) issue.

I also get a black screen using flatpak version from kdeapps repository. Version from Arch Linux repositories works fine on the same computer/system.
Same problem en KDE Neon with Plasma 5.12 LTS
I confirm this, black space where camera output should be on my Slimbook II user edition. Works fine on my thinkpad dev edition
