My Java project has been converted to a Kotlin Project After upgrading IDEA
Answered
After upgrading my IDEA to the community 2020.2.4 on Windows 10, I only see "Kotlin class/file" under "new", but not Java class in my Java project. A notification of "configure Kotlin" pops up on the right bottom corner. It seems that my java project has been converted to a Kotlin project with the IDEA upgrade. I am unable to find out how to let it stay as a Java project.
How to let the project stay as a Java project?

Please upload a sample project and the logs (Help | Collect Logs and Diagnostic Data) at https://uploads.jetbrains.com. Provide the upload ID.
Also check if installing IntelliJ IDEA 2020.3.1 from https://www.jetbrains.com/idea/download/index.html fixes the problem. It could be that the installation is corrupted and some default plug-ins cannot load.
