ProjectWise CONNECT Design Integration API Initialization exception

I'm seeing an OS LoaderLock exception while initializing the ProjectWise CONNECT DI API when calling aaApi_Initialize (regardless of the argument passed). I've never seen this before, but in the last 2 weeks, it happens every time it's called. The exception is catchable, but happens multiple times before it eventually clears. I'm concerned because it's the kind of exception that can result in a deadlock. Anyone else seeing this or know how I can keep it from occuring?
