Please Help! Machfive crashing to desktop

[akcrogan01]

Hi
I've spent days now trying to get machfive 3.2.1 working on my new HP Elitebook 850. Problem is when ever I select a sample to edit, (any sample from any instrument) Machfive will disappear. Also if I attempt to load an IR reverb I get the same result.
It runs perfectly on my desktop, I've reinstalled windows (twice now!), tried running from external and internal drives, tried running in admin mode, turned off bitlocker, tried running with out usb soundcard, I just cant figure it out.

The laptop is running an intel I7 1165G7 with 32gb ram and a 2tb nvme ssd with a Presonus Audiobox 44VSL usb soundcard.

Please any help would be so much appreciated feel like there must be a simple solution that Im missing.
cheers
derek
