After reading your reply I went back to make a short video of this problem because I believed we were working on two separate thoughts about the problem and wanted to clear things up and interestingly, upon running MSFS2024 today the problem had disappeared. Got no clue what changed because I haven't touched MSFS2024 since posting the issue. When I started MSFS2024 today and went up to the on screen menu to activate GSX it popped right up and loaded. If you recall, I described GSX was not loading at all before, it would just sit there and spin and eventually give the error described in my original post. Everytime I activated GSX that 'bar' would pop up along side of it while it was trying to load. In other words, the bar didn't show because of trying to close out GSX, it appeared when starting GSX, and would then remain on the screen thence. This is why I wanted to make the video so you could clearly see how the error occurred but unfortunately when I started MSFS2024 today to make the video I found GSX working for God knows what reason. So, not much to discuss at this point. If it reoccurs I'll get back with you. Thanks for responding though, much appreciated.
