Hi Victor. I'm Greg, an installation specialist, 9 year Windows MVP and Independent Advisor, here to help you.
Have you made any modifications of Windows?
I'll give you everything possible to repair the store:
See if the fixes here help:

Try running the Windows Store apps Troubleshooter at Settings > Update & Security > Troubleshoot.
Try resetting the Store cache:

If that fails go to Settings>Apps and highlight Microsoft Store, choose Advanced Settings, then Reset. After it resets, restart PC.
If that fails then reinstall Store. Type CMD in Start Search, right click Command Prompt result to Run as Administrator, copy the following code and paste it into the box using the Edit tools from Box's top left dropdown menu, press Enter:
PowerShell -ExecutionPolicy Unrestricted -Command "& {$manifest = (Get-AppxPackage *WindowsStore*).InstallLocation + '\AppxManifest.xml' ; Add-AppxPackage -DisableDevelopmentMode -Register $manifest}"
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. Then continue with the other steps to go over your install most thoroughly.
If nothing else works then do a Repair Install, by installing Media Creation Tool and then choosing 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.

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
