Windows 10: Several Errors relating to Microsoft Store and Gaming Services

I've been dealing with some issues for several weeks now and have managed to trace it to some kind of problem between my Microsoft Store and Gaming Services apps. I do not experience the issues every time I start my computer, but when the issues do occur, every 2 minutes on the dot, my Event Viewer reports a "Verbose" event from the source "Install-Service", Event ID 2005, Task Category "Service".UWAInstallWork::OnProgress Updating InstallAgentPdcActivationError: Unknown HResult Error code: 0xefffffffFunction: UWAInstallWork::OnProgressSource: oneco

Microsoft Service Blocking Games

What I meant by disabling Microsoft services was the following:

• Leaving "Hide Microsoft Services" unchecked, disable all services
  
• Check "Hide Microsoft Services", enable all services
  
• Un-check "Hide Microsoft Services", ensure most are still disabled (the ones that cannot be disabled were left enabled).
  

This solved the issue for both the games, and the display settings pane.

I have also tried a proper clean boot, disabling all non-MS services, and also disabling any MS services related to "Display", "Graphics", "XBox", and "Gaming" - this did not solve the issue.

Re-registering the settings app did not solve the issue.

Uninstalling the display driver with DDU and reinstalling with the latest AMD driver did not solve the issues.

Turning off non-MS services does not solve the issues (troubleshooting step 4).

Malwarebytes and Bitdefender premium both report no infections (step 7).

SFC and DISM report no issues (step 10).

New Local Admin account does not solve the issues (Step 17).

I am in the process of preparing the Repair Install, and will report back once complete.

Microsoft Store not working error Code: 0x80131500

Hi
Thanks for suggestions
I had tried all except re registering MSoft Store , but that unfortunately did not work .

Very intermittently use SurfEasy VPN, but last time used pre dated this build & problem by some time.

Have built pc systems /rebuilt windows op system literally100's times over 25 years for myself and others, and troubleshooted most known problems but this looks like a reinstall.
Not listed in Microsoft web notice as ongoing issue involving current build.

Only had Store problem once before since it was introduced years ago, and that was easily resolved !
