VocALign Project 3 crashing Pro Tools

[jacksbyrne]

Hey all,
I've run into an issue where trying to load the VocALign Project 3 audiosuite plugin causes PT to immediately crash. It's repeatable, happens every time in multiple sessions, and in both 2022.4 and 2022.7 (I've got both co-installed as I need .4 for the custom shuttle lock on audiobook jobs, pretty much everything else I do in .7). I've hit up Synchro Arts support, but all they've said is to make sure that I'm on the latest version of VAP3, which I already was, heard nothing else from then since (a week ago).

Mac OS 12.6
iMac (Retina 4K, 21.5-inch, 2017) (iMac18,2)
3 GHz Quad-Core Intel Core i5
8 GB 2400 MHz DDR4
Radeon Pro 555 2 GB

Pro Tools 2022.4 and 2022.7
VocALign Project 3 v3.3.2.2 (latest)

PT was installed and optimised as per the Monterey guide, so far I've trashed prefs, but I've not gone as far as a full re-install as I'm midway through a couple of projects, so I'm putting that off as long as I can. I can use VA Ultra/Project 5 as a workout but they're both dramatically slower in use than 3 so I'm hoping I can resolve this. If a PT crash log is any use I can attach that, got one saved from the last time I tested this. If you need anything else let me know and I'll add more info
