Intune Platform Scripts never target devices (0 targeted devices) despite healthy Intune environment

Update: During troubleshooting I found that newly created Win32 apps are receiving assignments correctly. Device-centric logs show the app assignment reaches the client and the Intune Management Extension processes it. The issue now appears to be isolated to Platform Scripts, which continue to show 0 targeted devices despite healthy Entra-joined devices, successful MDM enrolment, and a functioning IME. Existing Configuration Profiles, BitLocker, LAPS, Firewall policies, and Win32 app deployments are all working.
