I feel like I just committed a cardinal sin and installed flatpak on Arch Linux and now I feel kinda dirty but I really needed this one program and...ugh...embarrassing.

Your mistake was coming online and telling everyone about it.

honestly Flatpak can be good if you're not really into the AUR, especially now it has verified packages. sidenote, I'm on Windows as of recent since my music listening workflow works best there. But I might give the Arch-based CachyOS a whirl.
