SAS Enterprise Guide has encountered a problem and needs to close. Sorry for the inconvenience

Issue:

I had some issues with SAS EG, Whenever I open up SAS EG, I got the issue that EG needs to be restarted or closed. I did try to reinstall it, but didn’t help. Every time I launch it showed only Exit SAS Enterprise Guide and Restart option with SAS Enterprise Guide has encountered a problem and needs to close. Sorry for the inconvenience error message.
