[DX12] [Win11 ARM64] Machine crashes and restarts while trying to create a new project

DirectX12

-

Steps to reproduce:

  1.  Create a new project
  2. If editor is fully loaded without issues, leave it open for 5minutes to couple hours

Actual results: 
Machine crashes and restarts

Expected results: 
Editor works as expected and machine does not restart

Reproducible with versions: 
6000.2.15f1, 6000.3.3f1, 6000.4.0b3, 6000.5.0a4

Not reproducible with versions: 
6000.0.64f1

Tested on (OS): 
Win 11 ARM64
Windows Version: 25H2
OS Build: 26200.7462

Notes:

  • Does not reproduce 100% of the time
  • After running some automation tests it gets to a state where just creating a new project restarts the machine and can be reproduced multiple times
  • Also leaving editor open for a period of time (5minutes - couple hours) also results in system restart
  • Windows report a DPC_WATCHDOG_VIOLATION (0x133)
  • This reproduces on two different machines with same specs:

** CPU - Snapdragon(R) X Elite - X1E80100 - Qualcomm(R) Oryon(TM) CPU (3.42 GHz)
** RAM - 64.0 GB (63.5 GB usable)
* GPU - Qualcomm(R) Adreno(TM) X1-85
Ran Furmark and Cinebench for stress testing the machines and all tests pass

  • Forcing to create a new project on DX11 seems to be working as expected
