In ubuntu 22.04, I can't open magnet links from Firefox but I can from Chrome.
journalctl shows apparmor is denying the operation.

I thought it might be due to the snap installation of Firefox, so I tried installing it a different way:
sudo snap remove --purge firefox
sudo apt-get purge firefox
sudo apt-get autoremove
sudo apt-get install firefox
But, Firefox just re-appeared in snap list after this. It seems Ubuntu wants to use snap here.
So... what is the best way to fix this? I have no idea how to mess with apparmor.
For context, I am trying to run this application with magnet links:
cat /usr/share/applications/qbittorrent.desktop
[Desktop Entry]
Name=qBittorrent
GenericName=BitTorrent client
Comment=Download and share files over BitTorrent
Exec=/bin/bash -c "export PATH=/path/to/Qt/6.7.0/gcc_64/bin:$PATH && export LD_LIBRARY_PATH=/path/to/Qt/6.7.0/gcc_64/lib:$LD_LIBRARY_PATH && /usr/local/bin/qbittorrent %U"
Icon=qbittorrent
Terminal=false
Type=Application
Categories=Network;FileTransfer;P2P;Qt;
MimeType=application/x-bittorrent;x-scheme-handler/magnet;
xdg-mime query default x-scheme-handler/magnet
qbittorrent.desktop
I had to add paths to QT 6.7 to get it to work when launching this application from the show applications menu. But I don't think that is related to the magnet issue since I am getting the apparmor error.
