Seeing that this didn't worked, I purged the PPA using ppa-purge and had to reinstall the flatpak package from the repos.
Since then, I can't either find flatpaks using the Software Manager, nor can I install them from the Flathub by opening the flatpakref packages with it.
Installing Flatpaks still work on the terminal, however.
Another thing to note is that I purged the flatpak package before upgrading to Mint 20.3 and, only now, I've noticed the bug. I don't think this caused it, but thought it might be good to know.
