Multiple processes resulting in error code 0x80070490

Question

A while ago I tried to update What's App in the Microsoft Store and got error code 0x80070490. Around the same time I noticed that both the Xbox app and the Your Phone app stopped working - nothing happened when I clicked their icons. To try to repair the Your Phone app, I used the "repair" and "reset" options in System > System Components. I then did the same for the Windows Store. This seems to have resulted in these apps disappearing completely from my PC. They don't appear in the system components list anymore. I then tried to reinstall Windows Store from the command prompt using the code below. This also resulted in error code 0x80070490. What can I do?

Get-AppXPackage *WindowsStore* -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
