Hi, recently I received same crash report from online.
reason: "BUG IN CLIENT OF LIBDISPATCH: Over-resume of an object"
I think this is a system crash with CoreMotion(Gyro) for ios app on mac.
Can someone please help me? Thank you very much!
Over-resume object:
<OS_dispatch_source: source[0x600002b25580] = { xref = 1, ref = 1, target = com.apple.root.user-interactive-qos[0x10d0c55c0], ident = 0xffffffff, mask = 0x0, pending_data = 0x0, registered = 0, armed = 0, cancelled, deleted, timer = { target = 0x9de398bed, deadline = 0x9de398bed, interval = 0x1, flags = 0x0 }, kevent = 0x600002b25500, filter = timer }>
