iOS XCode sudden console spam: [default] IOConnectCallMethod (kIOHIDEventServiceFastPathUserClientCopyEvent): 0xe00002f0 (copySpec = (null))

Question

I have an ARKit iOS app that was working fine, the phone suffered a pretty hard drop, and this morning it's not capturing frames, instead it spams the console with:

[default] IOConnectCallMethod (kIOHIDEventServiceFastPathUserClientCopyEvent): 0xe00002f0 (copySpec = (null))
CVDataBuffer contains an invalid header

What does this error represent?

PS. Checked another AR app - also does not work with ARKit

Device reboot has fixed the issue, I hope this is a permanent solution.
