How do I resolve this?

The driver has something to do with one of my older WD external hard drives.

Thanks

Afaik you’ll need to either update or remove the driver or keep memory integrity off if the driver is needed but cannot be updated.

WD Drivers causing vulnerability on most of the computers: wdcsam64_prewin8.sys

Sep 21, 2022 - A couple of weeks ago someone from WD called me and guided me to the process of removing anything related to WD from my computer and removed any WD software. Then after rebooting the computer, I downloaded the latest software update for the WD and then everything worked out well...

I'm not having any problems with this driver, but IObit Driver Booster picked it up as an incompatible driver.

i have a M2 type WD580 blue. you will need to install the WD dashboard.
once installed you can update the firmware of the drive.
or, there is a registry entry you can add and alter to change HMB allocation size which is the problem that is causing the error.

Registry hack fixes WD SN770, SN580 Windows 11 24H2 blue screens (BSOD)

Certain WD SSD users are experiencing blue screens of death (BSODs) after updating to Windows 11 24H2. Thankfully, users have managed to figure out a Registry hack that fixes it.

This issue has been around since 11 came out.
Wdcsam64.sys has nothing to do with an internal Western Digital drive. It is a very old driver for an external HDD.

Just uninstall the driver - you don't need it. That's what I did back in August 2022.

it is only ever needed if you want to use the WD encryption software that WD supply with their external usb drives.

The WD SES Device only shows in Device Manager while a WD usb drive is plugged in. To see (and be able to uninstall it along with its driver) at any other time you need to tell Device Manager to 'View > Show hidden devices'.
