Indesign 2023 isn't exporting some of my images

I keep trying to export my document to a PDF and some of the rectangles weren't showing up so I moved them around in my layers and they are now, however now some of my images are not showing up in the PDF but there isn't a reason I can find for it. I've uninstalled indesign and reinstalled thinking that could be it. I've saved the document as different names. I've done so many different things and I just can't figure it out! I've never had this issue before, please help!
