In this situation, you might contact your users who can reproduce the issue and are willing to help, ask them to install the file provider profile, follow the guide to reproduce the issue and capture a sysdiagnose, and then provide sysdiagnose to you. From there, you can look into the system logs, and try to figure how the system behaves differently from the workable case (your case). The debugging process may take time, but given that you don't have a reproducible case, that's probably the way you can move forward. Best, —— Ziqiao Chen Worldwide Developer Relations.
