It doesn't work tried all the above tips mentioned.
It's obviously impossible to help you without knowing any context. You don't say if you use the SU10 Navdata API option and, of course, I cannot possibly say if you really tried ALL tips or, as you wrote, only the "above tips", or the ones you know about. So, please, always clearly report everything you tried, so we can say if you really tried "all" tips. For example:
- Is the Couatl icon still visible ? Does it disappear if you hover on it ?
- If it didn't disappear, can you fix with by right-click and "Restart" ?
- If it did disappear, can you restart it using the "Start Couatl for GSX MSFS" ICON on the Desktop ?
