OBS Studio Crash Log URL

No response

Expected Behavior

Tried launching the Advanced Scene Switcher

Current Behavior

Selecting the advanced scene switcher in the Tools Menu, produces the warning popup:

Loading of the following plugin libraries was unsuccessful, which could result in some Advanced Scene Switcher functions not being available:
/usr/lib/x86_64-linux-gnu/obs-plugins/advanced-scene-switcher-plugins/advanced-scene-switcher-mqtt.so
Check the OBS logs for details.
This message can be disabled on the General tab.

The logfile has more details.

Steps to Reproduce

1. Start OBS (from Menu or terminal)
2. Launch Advanced Scene Switcher from the Tools menu

...

Anything else we should know?

I've tried 1.33.0 and 1.33.1. Both produced the same result.

I'm using the OBS system package version, not flatpak

Can you check if installing libpaho-mqttpp resolves the issue?
I think this might be possible via sudo apt install libpaho-mqttpp3-1, but I don't have a Mint VM to verify.

I'm on CachyOS, KDE Plasma 6.7.3 (Not the x11 thingy either, just wayland) and I have exact same problem as @dexington
Also using the OBS installed from AUR - not the flatpak - as the AUR version was recommended.
For me, Advanced Scene Switcher starts, but it is not working right, especially with reading the cursor coordinates to swap between the 3 monitors. I'm new to the whole linux world but I can tell that "sudo apt..." anything produces an error saying command does not exist. IT is my understanding CachyOS is built on Arch Linux and that is why apt does not work here.

This is the one and only thing I hate with linux (Im a Windows exodus), no uniform way to do stuff, unfortunately. O.o
