âAdd Newâ â âBlueprint Classâ â âSelect Characterâ:

â âName it MyCharacterâ

â âSave and compile the new BPâ â âGo into a different BP, like the PlayerControllerâ â âGet Player Characterâ â âTry to find the Cast to MyCharacter hereâ:

If you donât get the Cast to here, then i would recommened you to verify your Engine Installation:

Or maybe redownload it completely. If this still doesnât fix the error, please create a new Question with all information you have gathered here in the âBug Reportsâ section of the AnswerHUB.
