Lastly this is the log

I exactly copy the code, by writing, from github link from lesson except the varrible names. I also check the issue several time by commenting out updated codes there is no an error.

I have any clue about the error log. I also tried to solve that by examine trough the codes.

Need a hand to solve my problem. Thanks.

@alexander_walker

TArray<FStiring> GetValidWords(TArray<FString>) const; //This code that I update just before Errors

You wrote FStiring here instead of FString.

Ohh, (facepalm) what a amateur misstake. Thanks for that.
