It seems this is same as #613

I am using Processing 4.3 in Windows 10 and this occurred to me too today. I did these and it fixed permanently:

1. (This step may not needed) I opened processing-java.exe file that was beside processing.exe file (This just opened a terminal and closed it fastly) (Maybe this step is not needed)
2. I opened Processing. After that, it opened an extra window that offered some examples beside main window of the app.
3. I just opened one of that examples. Then everything fixed permanently.
