PSDesiredStateConfiguration module v3.0.0-beta1 is broken on PowerShell 7.4.0-preview.4. (on Windows as well)
There is desync of DSC subsystem and PS engine.

Discussed with Andrew, he'll update the PS resource to detect use of 7.4 and report error to use 7.3 and link to a new issue to track the actual fix
