This problem could be caused by an incorrectly configured Chroma Key.

Unfortunately, there’s no way to restore those features, but there is a way to avoid that issue. To prevent it, you should create a personalized backup profile. To create a new empty profile, right-click on the cross option under the items menu and select “New Profile”. If you have already customized a profile and want to save it afterward, you should right-click on the cross and select “Save as new profile”.

Once saved, you can open the new profile in Coach Paint:
