All Windows Troubleshooters will not open

Hi........

HP Laptop 15-dy2048ca (2L7J7UA)

Windows 11 Home 25H2 OS Build 26200.8117

Intel® Core™ i5 processor

Installed RAM 8.00 Gb

 

First time here in a long time.

Anyways, my problem is that none of the Window Troubleshooters will open or run.  When I click the "Run" button I get two quick brief flashes from the touchpad cursor, but nothing happens.  The original reason I had to use the troubleshooters is that I had trouble getting update KB5086672 -26200.8117 to install.  But I was able to get the update to install after I ran an In-place Upgrade.

I've tried a lot of suggested solutions, but nothing. as of yet. has brought the troubleshooters back to life.  So far., in almost two days I have tried the following suggested solutions:

Check Path for Temp Folder

Restart Cryptographic Service

Run SFC and DISM Scan

Run Disk Cleanup

Check Group Policy

Try to run Troubleshooters in Clean Boot State

Enable or Restart Required Services

Flush the DNS Cache and Reset the Winsock Catalog

Disable Third-Party Security Software and Firewalls

Rename the Catroot2 and SoftwareDistribution Folders

Modify TEMP and TMP Environment Variables

Enable Troubleshooters in Group Policy Editor

Performed an In-place Upgrade.

Used a System Restore Point.

Surely there must be a solution to this that works.  Isn't there a download or a program where I can wipe out / delete the whole troublesome troubleshooters section and replace it with a troubleshoot section that works?

    You can run Command Prompt as an administrator, re-register the system DLL files, and then restart your computer.

    Run Command Prompt as an administrator, execute the commands `regsvr32 /i mshtml.dll` and `regsvr32 /i shdocvw.dll` to re-register the system DLL files, then restart your computer.
