Builder issues, screen goes black

Running on Win 10 Home, up to date, latest vs of the Builder, every time I launch the builder, mouse lags and then screen goes black. Have to hit Control, Alt, Delete to get the screen to come back on and then kill the app. Tried to uninstall and reinstall the builder, did not help. Any thoughts?

Is this before even opening a project? This happens immediately after launch?

What version of Win 10 do you have? I’m running 20H2 but I see 21H1 is available. Maybe try updating to the latest Windows release & see if that helps.

as soon as it opens, open by clicking on project file to open or if I click on the builder file itself, doesn’t matter, did work before, but I will try updating to 21H1
