Sounds like you manually updated C+, but SU uses C+ 2015. There’s also .NET Framework and be sure to update graphics driver too.
Are you using a laptop? If so, did you go to the Nvidia control panel and select the Nvidia card to be used with SU?
I notice you have Win 10. There are some issues with some unfortunate OS automatic updates too, but those issues seem to be limited to slow selection tool function on affected computers.
