    Hello.

    Open Security Center and make sure there is no third-party av solution installed.

    Sometimes, you actually have to add an AV package, then uninstall it to kick-start Defender into action due to a glitch.

    However, if no 3rd party AV and Defender will not start, this could be an indication pc has become infected with malware. This could also be cause of running slow.

    OP should scan pc with malwarebytes or similar

    are you using high contrast setting for themes if so turn them off/switch to a normal theme then try the security center (restart may be required) it's has been a problem for a while.
