TodayExtensions Unable to load in iOS 14

Hello engineer, I found my TodayExtensions runs well on iOS 13. 
Some users report the problems: When them upgrading iPhone to iOS 14, TodayExtensions appears at the bottom of the Today View, but it shows that “Unable to load” . You must restart the iPhone or download the application again before it can return to normal. The problem led to the loss of my users
But i cannot find any error in debug.I wonder if there are any new restrictions or mechanisms for TodayExtensions and how should i solve this problem?
same problem
add widgets page Can't find my app, but new widgets can find

Did that error go away? I'm getting the same error report, and I've seen it happen.
