It shouldn't (directly) affect ProtonMail — they're based in Switzerland, which is not an EU member and thus not bound by EU law.

That said, it's possible that this could be implemented in a GDPR-like fashion, where non-EU companies offering services to EU persons would be required to follow these laws.

It's also worth noting that the EU and Switzerland do have some bilateral agreements [1] for single market access, though, which involves it adopting some required EU law to facilitate this access; however, that should not be relevant for this specific issue.
