Standalone build: don't load my gamemode

  1. Did you fix the Has Blueprint Classses error? That could very well solve your problem if you didn’t.

  2. Looking at the error message:

Check your Map’s World Settings.

It’s looking for an asset named BExp_BaseGameTutorial in your /BaseGameTutorial/Experiences/ folder. Does this asset actually exist?

Also, when in doubt, delete all Binaries/Intermediates and do a clean rebuild. Sometimes Blueprints get messed up, especially if file names change, etc.

If none of these things work, all I can think is maybe read through my dev log, see what I did differently from what you did. It works fine for me, I have no issues loading lyra experiences with custom game modes.
