Unable to start powerapps in Web preview mode

As of today I am unable to edit powerapps in web preview mode(edit on the web - preview).  It begins to start, crashes after about 3 seconds and tries again (forever as far as I can tell).


I am using Chrome on Windows 7 sp1.  I have tried multiple accounts, multiple files and restarted the computer.  I have also cleared the cache from the last week.  None of these has had any effect.

The problem is the same today.  I'm not sure how to check a "JavaScript console for 404 errors".  Again, I cleared cache and made sure I had a completely fresh start of Chrome.  I also tried different accounts.

To check the JavaScript console, press F12 or open the Chrome menu, go to the "More Tools" menu item then click the "Developer Tools" menu item.


In the developer tools, click the tab labeled "Console", and copy/paste the content in a reply post.

Can you also provide the screenshot of the crash dialog that you are seeing?

There is no crash dialog.  It just keeps saying "working" in the tab titleand after about 2 seconds the process is plainly interrupted and it begins again.  This morning, at least it showed "Starting Powerapps" or some such message for a moment, but now that doesn't even show.



Have you tried @Ryanmch's suggestion to check the JavaScript console? If yes, how did that work?
