PyCharm startup fail - Internal error (java.lang.NoClassDefFoundError)

I installed a plugin for robot framework (robotframeworkplugin), restarted the PyCharm but it crashed and now it's not starting up giving ‘Internal error’ as the error

I have tried removing the files and folder in the plugins folder, restarted the systema and reinstalled PyCharm twice but nothing worked. Does anyone have any idea on how to solve this. This error below is a pop up and once I click on OK button, the pycharm exits.

The other pop up that is behind this error message is a choice to disable the plugin but can't click on it. Attaching the image here:

This is the error: 

Internal error. Please refer to https://jb.gg/ide/critical-startup-errors
