There appears to be something strange happening since some SDK Manager updates earlier.

Is your application small enough to easily copy and paste into a fresh app? That seems to fix it as a workaround.

Apart from the fact that appdata\local is not a recommended place for the SDK the latest SDK posted by Erel includes savedstate/1.0.0 not 1.1.0.

Try reinstalling a fresh SDK and resources from the link below, following the instructions exactly and using 7-zip or similar to decompress the archives as File Explorer can corrupt the folder structure of large archives.

Do not play with the SDK manager unless you really need to.

it happens when you update the SDK (in the week of 11 feb) . Just download the SDK again from link given on B4a site and it's solved.
