Yeah, Denuvo registers every version of Proton as a different computer. So when you cycle through a bunch of different versions, Denuvo sees you booting it on a bunch of different computers back-to-back. IIRC Denuvo’s ToS allows for 5 different computers to boot a game within 24 hours. So it locks you out for 24h, as an anti-account-sharing measure. It has hit the spotlight a few times recently, because of the Steam Deck users needing to cycle through Proton versions.
