C3422WE, firmware fail

Has anyone been able to resolve this issue? Using a Mac and a Windows, trying to update the firmware and the screen goes blank and then says update error. Used USB-C, USB-B, tried different firmware versions, nothing worked. Reason is with the Mac, webcam/mic does not work. Spoke to Dell support on the phone and they could not resolve it.

Yeah, ran into the same problem with mine. Ended up using an older Windows laptop with USB-A and ran the firmware tool as admin only then it worked. Mac never worked for the update. Dell support was no help either sadly.
