Sorry,we cant talk about anything other than Poser..So I cant help you...

Ok just check in your prefs in Zbrush go down to GoZ click poser let it do its things, (maybe it wont find it ) if thats the case browse to the exe file for poser. then when done close poser load a sphere in zbrush and GoZ it to Poser just to give it a test and thats it, The latest 2020.1 works with the latest version of Poser make sure you downloaded the support files for Poser (dont try and get the bare minimum like I did, theres things in there you need)
