Hi,
How did you configure the AppLocker Group Policy in the production environment? Have you tried to create a test user in a test OU in the production environment and then link a new GPO with
AppLocker settings to the test OU to check if it could work? Also, please let me know if the AppLocker policy could work when you disable the drive mapping policy.
Here is an article about how to troubleshoot Group Policy issue, hope this helps.
