Basic error message when playing game - No idea how to troubleshoot

Area_01 is my one and only map. Pretty simple really. Never had this before. Nothing refers to it from what I can see. How would I even begin trouble shooting this one?


Check your Level Blueprint. Also check your output log.

Thanks, it actually worked fine today when I reloaded my scene. Not sure what happened but yes, didn’t think to look into level blueprint.
