...on external changes and reload of the currently open project.
This is really weird as the same issue happened with a Visual Studio 2019 extension of another company, and after installing the new AlterNET 6.2 Studio, the same happens with your extension now. With the previous version, it worked.
See https://www.grapecity.com/forums/winforms-edition/extension-componentonelice for a detailed description - just replace the extension name ;-).
After disabling your Extension, project reload works again.

Sorry, I cannot reproduce it today. So, forget about this issue :-(
