Windows 10: My laptop keeps freezing with error code ffab LiveKernelEvent

I have a Lenovo Y540 with i7-9750H, 16GB Ram and GTX 1650. But lately it froze on me and checked Windows Reliability Monitor, and got this entry: SourceWindowsSummaryHardware errorDate‎2021-‎07-‎16 8:01 PMStatusNot reportedDescriptionA problem with your hardware caused Windows to stop working correctly.Problem signatureProblem Event Name: LiveKernelEventCode: ffabParameter 1: 3Parameter 2: ffffc3070cddd2f0Parameter 3: d28Parameter 4: 0OS version: 10_0_19043Service Pack: 0_0Product

Windows Hardware Error: "LiveKernelEvent", with code 144 and Locale ID: 1033

Repeated error

I have been repeatedly encountering the following error when my laptop freezes. It may occur multiple times during the day, and should take several minutes to recover.

More details

Per my best reflection, the hardware error occurs when I am using the laptop on its docking station. Here is what I observe:

• While using the laptop as normal, the "freeze" will occur and I can hardly operate the laptop: mouse cursor won't move continuously and Alt+Tab won't be able to switch across two windows.
  
• Shortly after (usually several minutes), things will go back to normal. Upon inspecting through the Performance tab in Task Manager, there had been no spike in anything, be it CPU, Memory or Disk.
  
• When I open the View reliability history tool, I will find another entry of Windows Hardware Error
  

Machine specification:

• Thinkpad T480, i7-8650U (newly replaced module thanks to the manufacture)
  
  • With the same pair of docking stations, an older unit of T480 has had exactly the same problem.
    
• Docking station: Thinkpad Ultra Docking station. Same issue has occurred on two identical docks with slightly different monitors and accessories.
  
• OS specification: OS build 17134.376.
  
• Most recent collection of "reliability report": a link to the xml file
  

Possible solutions

1. First, I would like to learn what exactly went wrong, hardware-wise: the manufacturer's support team did not bother too much with the precise error messages, and have ordered me to reinstall the Windows OS up to 5 times in total. [This is what they called "debugging".]
   

Please advise if you can decipher the recurrent "Hardware error".

1. Secondly, I will try to push the manufacturer to replace the docking stations, and see if the same "freezing problem' persists.
