Any answer/solution, please!
Hi, the best course of action is to contact Esri Technical Support if you haven't done so already. This is probably something that needs troubleshooting.

Thanks, Tim for your response. That's right, I contacted them indeed but no reply yet!
Meanwhile, could you try the following options?
1. Close all applications. Restart your system.
2. Try opening the APRX file from a fresh ArcGIS Pro instance? Project > Open. Also
3. Save As the project to a new location, and try opening the newly saved file.
4. Share as Project Package. Then extract the package .
