Windows 10: Cannot enable Core Isolation for Memory Integrity. Conflicting/Incompatible Drivers

About 4 months ago, my computer shutoff and restarted but would no longer show any form of network options. I sent it in to be repaired. They replaced the wireless card, motherboard from what I am told by the rep and fixed an issue with the TB3 port. I am trying to get this machine back to where it was but I keep getting this error. No idea on what to do to fix it. Any help I can get is greatly appreciated.

Core Isolation Memory Integrity fails to enable because of incompatible driver wdcsam64_prewin8.sys

Hi Lawrence I'm Greg, 10 years awarded Windows MVP, here to help you.

You can remove the unneeded driver as shown in first link or wait for the replacement WD is promising in the second link:

Here is more information about Memory Integrity to further understand it:

There are a rising number of cases of Memory Integrity recently, which according to a senior MVP and Moderator here is due to another attempt by Microsoft to certify manufacturer's drivers - something which has been tried and failed before due to some manufacturers ignoring it. It also appears to be buggy because its flagging Windows System drivers. Here is what you can do:

1) Make sure Secure Boot and TPM are enabled to get the full stable Security benefits of Windows 11:

Is Memory Integrity in Core Isolation important to run if "incompatible drivers" prevent that?

Recently Windows 11 Security began notifying me that Device Security needs action: Memory Integrity (in Core Isolation) cannot be turned on because of three "incompatible drivers." All three drives were installed from my ZTE Android phone. ZTE cannot provide updated drivers.

1. Is not running Memory Integrity really risky?
   
2. What would happen if I deleted the three specific drivers?
   
3. What are the drivers incompatible with anyway?
   

Not sure why this warning just started, as I have had the phone for several years without any issues.

Thank you.
