Export to Disk node crashes app on Android

Hello all.
Extremely frutsterating bug. Export to Disk node crashes app on Android (will test iOS asap)
Ive tried both 4.24 and 4.25.
Crashes in new, empty projects.
Does not crash on Windows.
Lost many days trying to sort this out, any help appreciated.
Alternatively, does anyone know of any other ways to save an image to device?
