Under the section of Download settings, check the box for Limit how much bandwidth is used for downloading updates in the background and slide the slider to 100%.

3] Re-register the Microsoft Store app using Powershell

Open Windows Powershell with Administrator level rights. Click on Yes for the UAC or User Account Control prompt that you get.
