Windows 10 reinstalling windows app store falls

I removed the windows app store for some reason. Then I try to reinstall it after removal, but it gives me error like this. I googled a bit but still cannot find relevant answers.

P.s. my firewall is okay and always running, so is windows updates. The services of both are running okay so it should not be the issues of these.

The answer is late, but I hope it will help someone. Had the same error today, but with the addition that the start menu wasn't working when clicking on it.

I could get it running again by enabling and starting the service "camsvc" (German: Manager-Dienst für den Funktionszugriff). It seems that the start menu is actually some kind of store app and needs that service.

Also the service provides the "windows.capability" and allows AppxPackages to be registered.
