Zorin right now is based on Ubuntu 20.04 and GNOME 3.36, which are pretty much dated. If his friend has a gaming rig, it would be better to look for a more up to date distro

This happens on Windows, right? What would happen on Linux, would the keyboard still work as it gets connected?

I’ve used pCloud for three years. Initially it is a lot, especially if you’re not sure if you will commit to them, but if you do, you have one less hidden big expenditure masked as subscription, which nowadays is valuable. I wish they released their Linux version through Flatpak and not Appimage, though
