Lutris, PlayOnLinux, Proton, etc. are all really cool. But, if you value your time and security, just keep a dedicated Windows system for gaming. I keep all the things I actually care about or don't want stolen on my Linux system with full drive encryption and I keep a gaming PC that has absolutely nothing I care about on it. The Windows system is never allowed to access my email, credit cards, or anything I care about in any way.
The small price I pay for having to manually type a Steam authentication code from my phone into the gaming PC is worth it to never have to worry about the insane level of insecurity and bugs from the gaming sphere. The amount of RCE in gaming is pretty bad. And, you know, sometimes your friends message you and want to play a game that is new and from a developer nobody can really trust.
Combine that with the fact that the first thing almost every game does is phone home to try and download new executable content and IMO you would be irresponsible to keep your important documents/credentials on a system that is also used for gaming.
