Interface with Atem Mini Pro and MacBook M2

I have recently streamed an event (OBS) .. without warning or even touching the Laptop, the output picture from the Atem turned blurry, in fact it almost appeared to change focus randomly. All cameras were effected, however media from the HD was perfect and not affected at all. I have since done every possible setting change, deleted and reloaded the software, updates .. every possible option I've performed ... but Nothing !!
Any idea's please on how to resolve this issue ?? Thanks in advance
