Hi Henry. I'm Greg, an installation specialist, 10 year Windows MVP, and Volunteer Moderator. If you will work with me I will be here to help until the issue is resolved.
I'll give you everything possible that works to fix the Store, based on helping to fix it a dozen times a day for years here. Even if you've tried a step, please do it over in this sequence:
1) Try updating Store apps:
https://support.microsoft.com/en-us/help/402625...
2) Right click on the time and date in the far right corner of the taskbar. Choose Adjust Date and time settings, at the top make sure the time is correct. If it’s wrong, manually adjust it and make sure the sliders for Set time automatically and Set time zone automatically are set to on.
3) Type CMD in Search, run as Admin, type in box and press Enter, wait until it confirms Services were stopped successfully:
net stop wuauserv
net stop bits
Delete everything you find in C:\Windows\SoftwareDistribution\DataStore and C:\Windows\SoftwareDistribution\Download.
Restart PC to restart these Services, or type in Admin Command:
net start wuauserv
net start bits
4) Try running the Windows Store apps Troubleshooter in Windows Settings > Update & Security > Troubleshoot.
5) Type CMD in Search box, Run CMD as administrator, type WSReset.exe and hit Enter. Or in the Search type wsreset.exe select Run as administrator.
6) If that fails to fix the problem go to Windows Settings > Apps > Apps & Features to highlight Microsoft Store, choose Advanced Options, then Reset. After it resets, restart PC.
7) If that fails then re-register the Microsoft Store:
Type CMD in Search, run as Admin, copy and paste into box:
powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRoot\WinStore\AppxManifest.xml
If you receive error "Cannot find path 'C:\AppxManifest.xml' because it does not exist" it means the Store was uninstalled, see here:

8) Clear the LocalCache Folder: Open Run by pressing the Windows key + R hotkey.
Copy and paste %localappdata% in Run and click OK.
Open Packages> Microsoft.WindowsStore_8wekyb3d8bbwe > LocalCache folder.
Press the Ctrl + A hotkey to select all content within the LocalCache folder.
Press the Delete button.
9) Type services.msc in Search box, choose Run as Administrator, from Services tab ensure that Microsoft Store Install Service is checked, if not restart PC.
10) If these all fail then go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done:

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files, and also Step 16 to test a new Local Admin account because of the serious and persistent problem with corrupted accounts. Then continue with the other steps to go over your install most thoroughly.
11) If nothing else works then do a Repair Install, by installing Media Creation Tool, open tool and choose to Upgrade Now. This reinstalls Windows while keeping files, programs and most settings in place, and is also the most stable method to advance to the latest version.
