Hi.
Rover uses webview from operating system. So it can work on Windows 10 and 11 OS without issue.
If you can screenshot your folder, I may find out the issue.
I have added compatibility to the nwjs calls required by RPG Maker MZ. So it should work now. Please download it again.
If a black window still appears, press F12 to bring up the error message and let me know.
