Cannot remove background from pictures

Im trying to use the background remover tool on an image that is 3024x4032 px but whenever i try, i get a popup that says "The minimum supported image dimensions is 10 * 10". i thought maybe this was an issue with this partiuclar image regardless of it being plenty larger than the required size, so i tried an image i had successfully removed the background from just earlier today. same message popped up. considered that maybe it was too large, but i constantly remove backgrounds from image of this size. i closed/reopened the browser, logged out, pasted the image onto previously fine canvases, etc. cant figure it out at all. is this simply a glitch? how can i go about fixing it?
