would you please be so kind and help me fix this

Protip: the series of letters and numbers that come just after the file and line number is the error code for the error you’ve found. Oftentimes, plugging the error code into Google will get you an immediate answer. Try searching for BCE0018 and you’ll see a number of sites (and some other UnityAnswers) explaining what’s going on.
