When jadx-core fails to properly determine the contents of a method, it produces an instruction dump that somewhat matches the behavior of a method. Intellisense does provide the feature to rename the arguments, and contents of the method, but any attempts result in a null pointer exception as per stacktrace above.

I would upload the apk, but github permits only 25mb uploads. Are there any other sources that I could provide the failing files with?

Fallback mode not suited to work with named variables, so I just disable rename for such args.
