Gamelift C# sdk 5.1.2 initSDK errors when trying to create a fleet in Amazon Linux 2023 using On Demand Ec2 c5.large instances

So i keep getting this annoying error saying "SERVER_PROCESS_CRASHED -- The server process exited without calling ProcessEnding(). Check your game session log to see why ProcessEnding() was not called." first then after "SERVER_PROCESS_SDK_INITIALIZATION_TIMEOUT -- The server process did not call InitSDK() within the time expected. Check your game session log to see why InitSDK() was not called in time." which keeps spamming in my event logs...

I pretty much did everything this user posted on https://repost.aws/questions/QUfHY8YVGoSgChHqO-bA2Phg/gamelift-sdk-5-1-1-initsdk-error-with-on-demand-instances and more... but i'm still having the same issue.

I tested locally on Anywhere Fleet and it successfully connected. However on the managed ec2 instances, I get the same error. I made sure to remove the server parameters on initSDK() before I tried creating the fleet. Also made sure my target frameworks were set to ".Net 6.0" and cpu architecture to "x64" on the sdk.dll build before I imported to my project and set my project target framework the same. I even tested on "arm64" build with a graviton 2 instance (c6g.large) and still get the same error... I cant remote access to the fleet with ssm because the fleet wouldn't go active.

With my project build im using visual studio 2022 and created the server executable using dotnet publish to linux-x64 architecture... and yes when i tested with arm64 which i used linux-arm64.

Is this a bug on the C# server SDK 5.1.2? or am i missing a step? This entire thing has been a huge headache and any help would be appreciated.

Thanks
