Multiplayer- cast to MyGameInstance node cast failed

The Situation
I am trying to get a basic multiplayer functionality working in my game. I am using the Multiplayer Shootout sample project from the Epic launcher as a functional, already set template. I migrated all of the files from the Multiplayer Shootout project to my project. I resolved other issues that come with migrating files, but the Cast to MyGameInstance is continuing to cast fail despite my efforts to fix it.
The Problem
The Cast To MyGameInstance Node fails, which results in the Multiplayer Menu Screen Widget not displaying (Find Game, Host Game). If this multiplayer menu widget does not appear, I cannot test the multiplayer functionality, since I am connecting via IP and not LAN , and the game cannot be hosted or joined.

Where can I set MyGameInstance class as the default game instance class?

“Migrated”…so…maybe you havent set MyGameInstance as a project’s default game instance class?

project settings → maps and modes

Let me know if it helped or not. And if yes then accept my answer to close this thead.

The MyGameInstance node is still cast failing. What else should I try or what else could be the cause for the fail?

It actually was working we just didn’t do something right. Thank you for your help!
