Autofucus Issues with A7R iv and 600mm F4 GM

I've found that the the 600mm F4 has been freezing up when combined with A7R iv what could be the possible problem? I've got latest firmware for camera and tried resetting.

I have no such problem with the same combo. However, the autofocus for birds in flight is not that great as I expected.
