Nintendo Switch build problem after updating...

I have updated to the newest Nintendo SDK and when using the latest build of the Solar 2D SDK 3726 I am able to build without an direct error BUT when looking into the build folder I do not have a single NSP file, but instead an empty one and a LOT of other files ending with .nsp.adf
We posted about this in the restricted DISCORD Nintendo Switch area and want to ask if someone else has this problem and a solution maybe?
Any help welcome!
Thank you!
