So what worked is I ran a winetricks --self-update. I cleared the winetricks cache before that multiple times. Then I was able to install it with winetricks --force dotnet48. Somehow it thinks it’s the wrong wine version when it is not. I had to rerun that to uninstall it because dotnet48 did not install properly. Then I reinstalled dotnet38 with the same command it installed properly. I don’t understand any of this, but I got it to work…
