Android Question App works in Release Mode, Crashes in DEBUG

[JohnC]

I am using B4A 7.8.

main.bal is present and works fine in release mode.

But when I try to run in Debug mode I get this error:

But if I turn on Legacy debug, it will run without any errors

Found the problem - the dir.rootexternal was write locked.
