Applocker Policy Update fail on Intune using Custom Template Configuration Profiles

Question

I'm using applocker using custom template profiles on Intune and it stopped working all of a suddedn as we added new files and as we save the profile after adding configuraiton settings of Dll.xml, Script.xml Msi.xml and StoreApps.xml. It gives invalid data error

{"error":{"code":"ModelValidationFailure","message":"Exception has been thrown by the target of an invocation.","innerError":{"message":"Exception has been thrown by the target of an invocation.","date":"2024-09-02T10:29:05","request-id":"a27f8abb-1540-43d1-a187-320e1645d844","client-request-id":"78d00871-8123-4463-b854-d509a08a2f37"}}}

Surprisingly the working xml files that are currently under enforcement is not getting reuploaded itself. We failed in creating a new profile as the error is the same.
