After clicking on the apply button in the second image, nothing happens. Ok doesnt work either. Does anyone know how to fix this problem?
in cmd: ruby -v results in C:\Users\mriedeman>ruby -v ruby 3.2.2 (2023-03-30 revision e51014f9c0) [x64-mingw-ucrt]
After switching branch, RubyMine was able to select the Ruby SDK as intepreter. I dont know why but after switching branch the problem was resolved.
Another suggestion is to remove the .idea folder after closing RubyMine. It will be recreated once you re-open the project inside IDE.
