JUCE 5.4.4 not compiling

I just upgraded to JUCE 5.4.4 for Windows and when I try to compile my project in VS2019, I get 113 errors in juce_RenderingHelpers.h. Many of the errors have to do with not recognizing the Rectangle identifier but I am not sure where to even begin with this problem. Does anyone have a clue what’s going on here? Thanks in advance!

Did you regenerate your project from Projucer?

Yes, I always open my project through Projucer. Is that what you mean by regenerate?

Have you included ‘Windows.h’ at all? There is a clash with Juce’s ‘Rectangle.’
