Compile for Android causes "The parameter is incorrect"

[Lounge Lizard Larry]

I'm trying to compile my first Android app using Qt. I'm getting really close but can't get past the error below. I don't understand the "The parameter is incorrect.".

I'm using SDK Version: 26.1.1, NDK Version: 19.2.5345600 because the tools I'm using (Felgo) requires/recommends these versions.

Can someone explain how to fix this? (I'm not sure if the Warnings are related or can be safely ignored). I should also point out that with each recompile the error remains the same, but the file (triggering the error) changes.

The problem is likely the NDK version, which is optimal for Qt 5.12.3, but likely not compatible with 5.15
