Developer Rig shows error on start

I installed today the latest version of developer rig. on install, everything looks fine.
But if I start, then in the browser I just get the Message
“TypeError: manifest.iconUrls is undefined” (see attachment)

If I close the message, I just get an empty page in the browser. Thats all.

Can anyone help?

Have you previously used the old version of the rig? The new rig isn’t compatible with the localStorage of the old rig, and doesn’t do any sort of checking or cleanup it just throws this error. If that is the issue for you, you can solve it be clearing your localStorage for the page by opening the console in devtools with f12 and use localStorage.clear()
