App Inventor Will not open my project?

So worked on my project this morning, but after lunch I cannot open it. Project name is Test and Tune Running Chrome on a windows 10 operating system. I get no error messages and the only acknowledgement of my "Open Project" request is that the Projects tab on the top bar blinks once.

ANy thoughts??

Restart AI2
Restart Browser
restart Computer

?

Restart Computer, Chrome and App inventor fixed the issue. I hade done Chrome and App Inventor restarts. I had not occurred to me that my Lenovo might have lost it's mind.

Back at it now.

Thanks
