When this issue occurs, the workaround approach that we follow is we go to the "Administration page" under Custom Extensions, click on modify and reupload the same bundled zip file and the custom policies start working fine.

Would you have any thoughts on what may cause this error to happen?

Please let me know if you need further information.

Thanks!
