Symantec Encryption Desktop is causing an error with Windows Security on a PC.

This PC has been recently upgraded to WIndows 11.

A driver named PGPdisk.SYS is showing incompatible with Core Isolation and Memory Integrity.

The driver version is 10.5.1.94.

Has any one else had an issue with this?

If so, please assist with remediation.

Yes, I had the same problem and reported it to Broadcom already.
As far as I know, they've filed an internal ticket to improve/fix this, but I have no official word on that.
If you are using any of the features that need that driver (Disk encrypxtion I assume), your only option is to disable the Windows 11 security features that it is incompatible with.
If you are not using those features, you can either ignore the error - or you can install PGP Desktop *without* those features using this commandline:
msiexec /i "Symantec Encryption Desktop 10.5.1 (64bit).msi" PGP_INSTALL_WDE=0 PGP_INSTALL_SSO=0 PGP_INSTALL_NETSHARE=0 PGP_INSTALL_VDISK=0
Note that you need the MSI installer ... If I remember correctly, I found that in the "full" download.
