Deesser Causes DR 14 to crash.

Like the title says.
I have tried inserting IK Multimedia's multiband deesser on an audio track and it works just fine while I'm still in the Fairlight page, but when I switch back over to the edit or color pages, playback immediately slows to a crawl, begins to stutter and then Resolve crashes within a few seconds.
I downloaded a freebie deesser (Lisp) as a test to see if it was IK's fault, but experienced the same behavior.
What could be going on here? Does DR hate deessing or something?
Yeah, I know my system is way lacking in the graphics department. But I have done projects that push up against the wall much harder without this issue.
I've even had one with two EQs, compressor, limiter, expander/ gate, RX elements AND Acon Digital noise reduction as well as a convolution reverb piled on top of each other.
