Inkscape to sheetcam issue

I have 3 different designs on InkScape I have created. When I open them on SheetCam I get a blank screen for all three. I can open files I created before and even after these three but just those 3 won’t pull up. I don’t get an error message just a blank screen. No layers up on the left bar. I’ve tried creating a new file using the same image and same results. Help me Internet you’re my only hope!!!
