Unable to process binding



can't currently open my app in edit mode (the published version seems fine). The error code is


"Unable to process binding: attr: function() { return { title: properties.Tooltip, 'aria-label':accessibleLabel, 'ariadescribedby': descriptionId} }


Message: accessibleLabel is not defined"


How can I solve this error?

If I can't open the App, my colleague can open it and vice versa.

but there is some issue as even i manage to open it. i close and open again i get the same error. tried restore to previous version have the same issue. Tried save as different app and still get the error.

Getting the same error, hoping haven't lost all the work! Published app seems fine but can no longer edit further. Restore makes no difference. Please post any updates if anyone hears anything.
