I want to check the classification accuracy with the confusion matrix, but the tool is not working. I've done this previously in early versions of ArcGIS and it worked. What could be the reason?

One thing I do when I see strange things like this is rename the ESRI folder to ESRI_OLD.  These folders are located in your C:\Users\<user_profile>\appdata\local and C:\Users\<user_profile>\appdata\roaming paths.  If it's worked in the past, I wonder if there's something "odd" here.

Hi! Сonfusion_matrix, matrix, accuracy, or something like that.

Are you saving it to a folder or a .gdb? If saving it to a folder, put  .dbf after the name, and keep the name short, sweet, no special characters, no spaces [the usual].
