There are numerous threads on this topic already. Have a little search. Basically the problems stem from bad Windows updates and bad Intel graphics drivers. Very likely in your case a Windows update made the Intel graphics the default for SketchUp. You’ll need to go to the Nvidia control panel and make the Nvidia card the default for SketchUp.
