Resolved my issue with Editor window missing after reloading UGSPlatform on a Macbook using MacOS Catalina

[HomebuiltCNC]

Just thought I'd add this note in case anyone else has this problem. I spent two solid days trying to work out what was going on.
I accidentally loaded a nightly build and probably incorrectly disallowed a permission request from the OS during the process. I deleted the app and then reloaded 2.0.21. I then found the editor window was missing and only script was in the window when attempting to load a usgd file. A number of file management commands were missing from the tool bar etc. I tried deleting and reloading a number of times, and after a number of other checks on permissions etc I finally did a full review of the library files and folders to remove any residual components and also found a folder titled "Saved Application States" that had two files starting "net." I deleted these two files and voila, the app then loaded without problems.
Maybe this might be found by someone striking the same problem. I presume this discussion can now be closed.
A great app guys.
