Class file editor source not found

A couple of weeks ago I noticed an issue with my script that I cannot seem to resolve. I have not changed or edited my script or any files on my laptop, so I don’t know what may have caused this. When I go in to make minor changes in my script (usernames, pwd’s, etc.) I now have an up arrow on the left and when I click on it, a window opens for Script.class and says Class File Editor Source not found. It then continues on to say

*The JAR file C:\Users&&&\Desktop\Katalon_Studio_Windows_64-5.8.6\Katalon_Studio_Windows_64-5.8.6\plugins\org.codehaus.groovy_2.4.7.xx-201611170128-e46\lib\groovy-all-2.4.7.jar has no source attachment. You can attach the source by clicking Attach Source below: *

I have not posted before and am limited by learn as I go knowledge, so please, if I am in the wrong area, direct me to the correct place.

Thanks

Can you post some screenshots of what you’re seeing? Thanks.
