AWS mgn not support kernel 6.1.41-63.114.amzn2023.x86_64.

Please test this again as you have time. I have been able to now successfully install the MGN agent on a Linux 2023 image.

I have been able to reproduce this problem although I do not have a fix at this current time. Will reach out once I receive more information.
