SolidWorks 2020 crashes constantly

I purchased the full student version of SolidWorks 2020 today, and I'm finding that it crashes within minutes. It doesn't seem to matter what I do. It crashes during sketching. It crashes in parts. It crashes in Assembly. In crashes doing in-context editing, and it crashes applying an appearance to a face. It seems to be essentially un-useable. Any help would be appreciated.
