Below are the steps I followed.
Windows 11 Home Build 10.0.22000
wdcsam64_prewin8.sys
driver date: 10/8/2015 1.1.0.0 oem78.inf
driver date: 11/29/2017 1.2.0.0 oem54.inf
Lenovo with AMD Ryzen CPU
The drive was running FAT32 but have converted to NTFS but no change. The drive is working fine but preventing memory isolation from working.
This is what I experienced and how I fixed it. Please be careful. If you’re unsure about these steps, then seek assistance.

I followed instructions in the article listed below and improvised some as well.
This was a rough draft of my steps.
Remove external drive
Place laptop in Safe Mode
Open Device Driver
Select View and by Connections

Go to Windows/inf and delete .inf files located above.
Exit Windows and restart
Once within windows, plug in external drive.
The drive will require the driver needed and will install it. Mine was from 2006.
Running Windows Update will find a device driver for WDC_SAM under Options. Initially I did not install the driver, I later went back in and installed it without issue!
