SOLVED PXE Task Sequence imaging error

[whatworks]

Our stable environment had PXE imaging stop functioning properly and I have not been able to figure out the cause. PXE gets a successful TFTP connection and grabs the wdsmgfw.efi -> loads the NBP and prompts user input (enter) -> gets to the WDS screen and stays stuck on Waiting for Authentication and the SMSPXE.log shows this over and over:

Failed to set device element BCDE_DEVICE_TYPE_BOOT_DEVICE for BCDE_DEVICE_TYPE_RAMDISK_SDI_DEVICE SCCMPXE 11/1/2023 12:01:55 PM 5140 (0x1414)

Failed to create object which represents the ramdisk we will be using to boot into the WIM file SCCMPXE 11/1/2023 12:04:01 PM 7016 (0x1B68)

Repeated every 20 seconds.

I have tried re-creating the boot image, new task sequence, refreshing the DP/PXE, updating ADK/PXE version, downgrading ADK/PXE version...

Any assistance would be greatly appreciated.

Sophos seems to have been the culprit. Once it was disabled, PXE was able to continue.
