I do use Proton often, and it seems it was set to New Jersey this time. I live in the US, and afaik, my state doesn't have mandatory age checks for all websites.
Edit: NVM, my state has signed and will soon enforce a social media age check. Guess I'll VPN to other states and countries 💀
Even when I disable ProtonVPN, the same things happen. Freetube and Invidious say may be inappropriate, mpv crashes (non age restricted videos play fine), and even YT ReVanced throws a fit on both my accounts. On browser, both Librewolf and Ungoogled Chromium get hit with the same "verify age" button. On Fedora Linux.
