I read on the other thread that the software preventing you from using linux is a video conferencing app. If you could give us more details on what this application is maybe some of us might know a more precise way around the problem, but with so little info at least I am stumbling in the dark.

As for general purpose advice, many people already said what I would have: either use a VM (mind you if configured properly VMs can run quite fast) or use remote desktop and somehow pass your webcam/microphone to the remote pc (there are USB over IP solutions out there that basically allow you to pass a USB signal over the network, like this for example; I haven’t actually tried it myself but it does exist).

You can take a look at the Linux VR Adventures Wiki, it’s the best resource available right now for VR on Linux (full disclosure: I’m biased since I’m part of the lvra community/devs 🤓)

The application needs to speak a protocol to be able to use it. If you use a X wm your apps need to be able to talk X’s protocol to work, if you use a Wayland compositor your apps need to be able to talk Wayland’s protocol (or run on Xwayland, which is basically an X server that runs inside Wayland).

The wm/compositor abstractions only work if your apps know how to use them via the correct protocol

Sorry if it’s not a direct answer, but I can suggest you try inkscape instead. Of course it’s a much more powerful program, and that comes with it being possibly a bit harder to grasp and definitely different from publisher, but it should be very easy for a beginner to make a simple birthday card collage.
