As a follow up on this issue for anyone who may stumble upon it (including Dell service techs), the link above for the known issue is for the Dell Command Update Windows Universal installer. This issue is for the Dell Command Update Classic installer. I continued troubleshooting with Patch My PC support and even performing a manual installation outside of Intune/Patch My PC fails with the same error. I am currently/still working with Dell support to troubleshoot the cause.
