exec /opt/.sagemakerinternal/conda/kgw_variant: exec format error

I've been trying to use my own custom image in SageMaker Studio and I always get the same error when trying to associate a notebook to the kernel (as seen in SageMaker Studio) :

Failed to start kernel
Failed to launch app [xxxxxxx-ml-t3-medium-176855f5e1df73edeeb33d0c81f0]. InternalFailure

And, the only log event seen in CloudWatch for the image is:

exec /opt/.sagemakerinternal/conda/kgw_variant: exec format error.

At first I thought it might be a bug in my container, so I have carefully checked all the steps described in DEVELOPMENT.md.

And finally, to try to discard a bug in the platform I tried to use the examples echo-kernel-image and python-poetry-image without modifications from the repository and in both of them the same error occurred.

I have also tried the tf23-image example, and it works, so I have been comparing the images and my feeling is that it could be related to the base image (the operating system used in the container): echo-kernel-image and python-poetry-image are based on debian and tf23-image is based on ubuntu. Could that be the issue?

Could you please confirm that echo-kernel-image and python-poetry-image images are working (as is) in current SageMaker Studio version?
