Wappler 2.8.3, Windows 10

I keep getting the “No App Root Found” message… then I appear to fix it, then a few hours later, without doing anything anywhere near the root, it comes back…

Is there anything obvious from this image that may show where the issue is? I do have an action on page load… could this be causing it?

Thanks,
Antony.
