SQL Server VSS writer doesn't show up in vssadmin writers list

Hello everyone, I have an issue after a recent CU update that seemed to cause my SQL Server VSS writer to not show up when running vssadmin list writers. It DOES show up in services as running / automatic / local system. The local system user has sysadmin permissions in sql. I've tried restarting the service, server, and verifying permissions and no luck. This is an issue because my backup service uses VSS and its not detecting the server at all due to VSS not running in the writers list. The only thing I think i haven't tried is uninstall the sql server vss writer due to my limited knowledge of sql. Can someone advise what else can be done here?
