Random BadTokenExceptions

[binarynoise]

I recently get this Exceptions, seemingly random (nothing in the magisk logs)

android.view.WindowManager$BadTokenException: Unable to add window -- token android.os.BinderProxy@19b999e is not valid; is your activity running?

I captured this Exception with scoop

I don't see anything related to Magisk here

I do, because it's the magisk manager that crashes. About 10 times in the past 4 days. And I don't think, that this is normal

No it's not, but you did not mention anything about the Manager crashing in your original message, and the log has nothing to do with Magisk.

If there's really a bug with the Manager you'll have to show what it is...
