The same thing has been happenning to me, except I'm using a Mini. When pres the FX button for lumetri colour, I can see the clip again. Delete your lumetri and reapply after you've stabilized. This should clear things up. Cheers, Brian
Both Warp and Neat use a TON of RAM and also GPU vRAM. That might be the issue here.
I note you have both Lumetri color and Warp applied here. With a low-powered machine, it's better to run them separately. Perhaps either Warp, do a render & replace with a good intermediate codec like Cineform, ProRes, or DNxHD/R, then do color. Or ... the other way around.
Either way, the clip is "clean" of any effects when you apply the next on.
