Product: HP ZBook Ultra G1a 14 inch Mobile Workstation PC (AY8K8AV)
Operating System: Microsoft Windows 11

Hi, I am using HP Zbook Ultra G1a with AMD Ryzen AI MAX 385 processor, and its integrated GPU.
When playing youtube, the whole PC freezes (occasionally). Then I have to force restart. In the Event Viewer, I see this error (I am not sure if this is related or not):
The IOMMU has detected an error.

Device: 0xC100


The issue has been since I started using this laptop, which I bought recently.

Currently, I am only seeing this issue in video playback (youtube or other video websites) on any browser.

I did update my drivers from HP Support Assistant app, but the issue still persists.

Seems like some issue with some driver. Can you guys please help?
