So, as title says it just worked and stopped working after the update. I get an update on testing and it stopped working, days ago. Then I decided to come back to stable and it worked again for few days until the latest update. How my problem is different from a similar post posted in august? Because in my case webcam is working perfectly in the browser, telegram and even cheese. The problem appeared only after the update of kamoso. If I run kamoso with sudo the webcam is working.
This is the output when i try to launch kamoso from terminal

 ~ >>> kamoso

For the rest manjaro is working perfectly, and with kernel updates annoying bugs like touchpad not working after suspend aren’t frequent anymore, at least it didn’t happen from weeks yet.
Thank you in advance to whoever will try to help.

It looks like the programmers upped the dependency of QML without fully testing it. It is saying that one of the functions they are implicitly using is no longer able to be used that way.

You might want to raise the issue here: Bug List

Might not be related but wonder if the same issue is what’s affecting Webcamoid …? I’ll investigate (and make a separate thread as appropriate). I’m out at the moment and don’t have the USB camera with me to do a test. Still works with the built-in webcam.

Then is just some error they get in the new version, it seemed odd nobody else have this issue. The only one I saw is this. I will report it with the output as I did here, maybe they will fix it or come out with a solution. Thank you.

This was really interesting, I guess they are using same libraries but in this case the app crash and close. Here is the output:

though the webcam I’m using is the built-in webcam, just to make things more complicated
