Sorry but no.  I can only sympathise.  Sometimes you just have to wait =
for a while and then it figures it out after a few minutes. =20
The cache has been driving me nuts lately, I haven=E2=80=99t started =
using CC 2018 yet but 2017 has been really problematic.  I actually =
wonder if it is just the cache or if there are deeper issues with the =
playback system.  Sometimes it feels like AE is running two or three =
things at the same time and they=E2=80=99re all out of sync.

I have a project for sale on videohive that seems especially good at =
breaking the cache system.  For a while it was so unreliable I wondered =
if I could even offer it up as a retail product.

FWIW I don=E2=80=99t use a disk cache.

Of course there=E2=80=99s always the possibility the one-frame is meant =
to be there.  Check for shy layers you=E2=80=99ve forgotten, effects =
that reference other layers, motion blur (this is a biggy for artefacts =
that only show up in final renders) , check things like composition =
shutter angle and phase.  Frame blending can also cause funny results =
for 1 frame.
