After I accidentally changed the java version (downgraded it from 17 to 11) from settings menu, my PyCharm wont start at all. I even tried to remove it and reinstall it but nothing happens so far. Getting the below error after reinstalling pycharm. I know I can delete all the files related to Pycharm in my ubuntu system, and reinstall, however I am looking for some elegant solution where I can bring back to the previous state.
Error:
$ pycharm-professional
