Why isn't the invidious redirect extension working?

Windows 10 22H2
Ryzen 2700x
RTX 2070
Asus ROG STRIX B450-F GAMING ATX AM4
Firefox 111.01 with Arkenfox file

When I put invidious.privacydev.net in the extension and open youtube through brave search I get the “Hmm. We have a problem finding that website” message. But if I only make it redirect to privacydev.net I get redirected to that website without any problem. Do you think it is because of ProtonVPN or Arkenfox or do you think there’s a problem with the extension?
