Error 615 during TS Install Application with ConfigMgr 2509

[Kevin Severud]

Just updated Configuration Manager to 2509 (from 2503) and now seeing that PMPC apps that had been installing fine during TS are getting error 615.

For example,
The task sequence failed to install application PowerShell Core (x64)(ScopeId_ED403E82-612E-4726-AD70-11BCD8C8EB51/Application_b1cac6f0-c2ab-4569-a180-f95f7be61495) for action (Install Applications) in the group () with exit code 615. The operating system reported error 615: The password provided is too short to meet the policy of your user account. Please choose a longer password.

Anyone have thoughts on what might be happening here?
