UE5/VS 2019 with Gamelift SDK build error

I did not see any questions on this forum addressing the problem I got, so I will be the first to ask if its a question or a bug.

I have VS 2019 for UE5 (UE5 tends to through a fit if you use 2017). I just downloaded the Gamelift SDK because I wanted to use AWS for a game server fleet. It looks like an awesome choice!

However, following the instructions here, I wasn't able to build the project. I got an error MSB8066. A quick Google search yields 1 post on Stackoverflow about it made SEVEN MONTHS ago. I wanted to bring attention to it since UE5 is the latest and greatest from Epic and this is a massive road block to development with AWS. Btw, i ran the EXACT line of code mentioned in the stackoverflow question and was able to reproduce the problem perfectly.

Thank you for any advice and help. Hopefully this problem was already resolved long ago, and Google just refuses to show me the light.
