Art Board issues

For context I am working on a project for college and I am making stuff at home, on a laptop, with connected creative cloud. I worked on making these pieces the whole weekend and I come back to campus to continue to work, this time on my PC, which can handle illistrator just fine, but find that the files won't export. I come to find out that my artboards are missing in all my files, not just the ones that I worked on over the weekend. I try to put a new art board in, but it won't place. I go to the artboards window and I can't add a new art board either. The only way I have found to "fix" this is to copy what I made and paste it into a new file, but after exporting, saving, and reloading illistrator to see if that fixed things, the art boards were gone again. Has anyone found a solution to this? I'm pretty sure this has been happening to me since I got it on my pc, I don't know why this is happening either.
