I have same issue. Maybe 4 times out of 10 when loading up a session with any UA plugin, PT hangs for a LONG time. Sometimes just hangs indefinitely, sometimes I get the UA error code -38 (after close to 20 mins of spinning wheel). I've narrowed it down to some kind of communication issue with the UAD cards and the Magma exp chassis. Probably fighting the HDX cards in the chassis communication with the computer or something along those lines.

I should note the 4 out of 10 times is from boot. I typically turn the system off at night.

I'm booting off a Pcie SSD so I only have 1 Pcie slot free, but 2 UAD cards. I tried splitting the cards (1 in the Mac, 1 in the Chassis) but that made it worse.

Prob need to ditch the Pcie SSD Boot drive and then move the UAD cards into the Mac... Anybody else with similar issue and alt solution?
