Hi Tristan,
I'm Paul and I'm here to help you with your concern.
Can you try to reinstall it manually?
Open File Explorer > go to C:\WINDOWS\System32\SecurityHealth > click 1.0.2207.20002-0 > double-click/open the Microsoft.SecHealthUI_8wekyb3d8bbwe.appx > click Reinstall.
I hope this helps. Feel free to ask back any questions and keep me posted.
