I got Helldivers to work by making it open in windowed mode rather than full screen, then making it full screen once it opened. Seems to be a common issue with it. someone on protonDB mentioned it iirc.

Rider has just been better in every way imo. I haven’t touched VS in years.

It does cost but you also get a permanent licence for the version you paid for so you can pay for a year and keep that version.
