Sigma MC11 questions

I found a great deal on a7RIII yesterday.  However i seem to have issues where camera locks up using mc11 and canon 100L or 50 1.8 STM. It happened with both lenses using AF-C. Is that normal? Camera stops reaponding for several seconds sometimes it took a photo finally sometimes i had to turn it off and back on.  I don't  think it happened with sony G 24-105 OSS which  is my only native  lens now.

Im pleased to  say AF is super quick with both 50 and 100 however canon 100-400 is significantly  slower and hunts much more.

Is there a firmware update for sigma adapter or how would i even update it if there was one

Thanks
