Best would be to start with a fresh user directory and when this problem happens, provide the log files (where the user directory is is described in the About box).
"No valid Java Platform found for key: 'JDK_11'" For that, probably, go to the Project Properties dialog of your project and register the JDK you're using there. If you can reproduce with a fresh user directory and a project created from scratch, please write back and say so. Gj On Thu, Dec 3, 2020 at 5:30 PM Mark A.
