Internal error on startup

Windows10 Edge browser.

Every time I attempt to start appinventor from a new instance of Edge browser I get an internal error.

My work around is to simply start a new tab and start appinventor in the new tab and appinventer starts and works perfectly.

This has not just happened once or twice but dozens of times.

I have clicked on the ok button of the notification box several times.

Try with Firefox. Edge is not really recommended to load App Inventor.

Thank you.
