What method did you use for install? Ubuntu shows a snap version in their store, its not official and maintained by Ubuntu not us. We have found it has a fair few issues that aren't present in other packages.

I would reccomend downloading from flathub which you would need to setup manually on Ubuntu. Otherwise our appimage on our website https://prismlauncher.org

We do also have a third party build that is more stable then the snap for Ubuntu on makedeb.

How does it fail exactly? As I recall, flatpak aren’t distro dependent.

have you tried the flatpak? it should include any dependencys you need. im on arch and it works great from the aur, but i know that does not really help you.
