Mark with red on the timeline the clips that need to be analyzed !!!

Ok, I'm simply a practical guy. And as Warp is the heaviest resource hog effect ever created, even more so than Neat Video Noise Remover, it ain't computer friendly so to speak.

So as soon as I have a usable Warp analyzed, I immediately do a full render/replace "with handles" option on any such clips in a sequence to something usable like ProRes 422. As you can "restore unrendered" if you need to change the clip, but if not, it's done. No further hassles.

I actually don't understand leaving a bunch of Warp clips just sitting on a sequence. It's too likely to slow down or completely mess up on export.
