I am, unfortunately, not terribly computer literate, so I'm hoping I can get some help.
I downloaded GIMP to fool around with some image creation for an RPG I'm running. After attempting to use the Layers function for the first time, I started running into an issue where whenever I click on the image I'm trying to edit, I get the error showing below. I can't figure out how to get around it. Even completely exiting the program and starting a new file results in the same issue. Before the first time I attempted to use the Layer function, I didn't have the issue.
Any suggestions on how to fix this?
