Welp, after much digging

Welp, after much digging around I finally found the answer that worked for me. Posting the link in case anyone else runs into this problem.

As a last resort that I thankfully didn’t have to do, I also saw a few sites that suggested removing WMC then adding it back. To do so, go to control panel > programs and features > turn windows features on or off. WMC is under “Media Features”, uncheck the box. Think you have to reboot afterwards. Then repeat the process to turn it back on. Hopefully the above link will do the job though so this won’t be necessary for anybody.
