Windows Store and Windows Calculator won't open

I have a HP laptop that has a messed up Windows Store and Calculator. Windows store does nothing, I tried reset, terminate, troubleshooter, and PowerShell reinstall. The Windows Store shows an exclamation mark. Both are greyed out. The calculator says “this app can’t open. There’s a problem with calculator. Reinstall the application from its original install location or contact your administrator”. I have the latest version of Windows 10. Does anyone know how to fix this?
