can someon help me with this error, i keep getting this when i try to build my project, just started a new project thought that it would help but i keep on getting the same error, when i dubbel klik on i get the error message in the image i uploaded. i can’t recall deleting, moving or renaming something.

Something is corrupted/missing somehow. It is probably easiest to just start a new project and move your files into it.

Could it be this (public static int[,] DitheringArray; ) that causes the CLR_E_FAIL error?

Yes, multidimensional arrays are not supported. You need to use jagged arrays

array[][] instead of array[,]

yep is fixed. :slight_smile:
