NSInternalInconsistencyException on iOS 13.2.3 when connecting to qBittorent 4.2.1 TL;DR:

[Assert] UIView animation API is being called from a background thread. Performing any operation from a background thread on UIView or a subclass is not supported and may result in unexpected and insidious behavior.
BarMagnet[17998:2644184] This application is modifying the autolayout engine from a background thread after the engine was accessed from the main thread. This can lead to engine corruption and weird crashes.
BarMagnet[17998:2644184] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Modifications to the layout engine must not be performed from a background thread after it has been accessed from the main thread.'

https://stackoverflow.com/questions/43071654/modifications-to-the-layout-engine-must-not-be-performed-from-a-background-threa This question on stack overflow verifies that this is an issue introduced in iOS 13

wasn't a problem in iOS 12, but crashed my app in iOS 13

And somewhat related to calling UIKit from a background thread
