Realtek drivers gets uninstalled on bootup

I have this very weird issue with my PC every time I boot it up. My Realtek audio drivers get uninstalled. I have no idea what is causing this. I scanned my pc for viruses, no viruses found using Malwarebytes. Checked my processes and I havent found anything suspicious. Anyone had this problem? If so, is there a fix?

Maybe an old uninstallation run has got stuck at doing its thing on every startup. You can look for stuff that starts automatically with software like Autoruns.
