HP Pavilion 16-af0000nh unable to shutdown properly

[Phyis]

My laptop (HP Pavilion 16-af0000nh - AY7G5EA) does not always shut down properly. When I click the shutdown button, the process starts as if it is shutting down, but after the screen goes dark, the power light remains on, and the fan continues to run. I can only fully shut it down by holding down the power button.

In the event log, an error message appears every second:

• Source: usermodepowerservice
• Event ID: 12
• Task Category: 10
• Description: "The process C:\Windows\System32\WUDFHost.exe with ID 1580 has reset the policy from {381b4222-f694-41f0-9685-ff5bb260df2e} to {381b4222-f694-41f0-9685-ff5bb260df2e}."

If I change the power plan from "Balanced" to "High Performance" or "Power Saver," the error message disappears from the event log, but the shutdown issue does not always resolve. Deleting the "Intel Innovation Platform Framework Processor" in Device Manager also stops the error messages, but it reappear after reinstalling. I have tried different versions of the Intel Innovation Platform Framework Processor Participant drivers (Core Ultra 5/7 series):

• 2.2.10001.3 Rev.C
• 2.2.10001.3 Rev.B
• 1.0.11404.41023 Rev.A

The error message appears with all drivers. I suspect this might be related to the shutdown issue.

• BIOS version: F.31 Rev.A
• Fast Startup is disabled.
• SFC and DISM scans found no errors.

I purchased the laptop in August 2025, and the issue started after a fresh installation of Windows 11 and some updates. Another user reported this issue earlier this year, but I did not find a usable solution: https://h30434.www3.hp.com/t5/Notebook-Operating-System-and-Recovery/New-laptop-freezes-on-shutdown/...
