What Media Codecs to you have? We use .mxf long gop. I assume some troubles from this side or maybe the blackmagic Decklink card we are using for video playback.

Now I'm facing with this error for the first time. I'm working with expression drivem offset path on shape layers. I have to switch them off and it's working. But I need to find another way to visualize what I want.

They were corrupt AI files but even after reloading them the error kept happening. I copied and pasted my elements into a new AI file an resaved under a different name and tried again and nothing worked. I cleared the cache, unsyced my fonts, resynced, updated my driver, changed AI preview to CPU and off, updated AE and AI, nothing.
If this is happening to you even after doing all of this, do your AI files have links to PSD elements? Remove those elements and try again. I deleted all those layers that were just linked assets and the error stopped. This project got collected and passed around 5+ times, so Im sure along the way those assets got corrupted, but the vector parts themselves were fine, obviously. I just had to manually replace the missing AI layers that were originally the PSD link, and manually replace them in AE with the ACTUALY photoshop file, and not just the AI layered version that comes in when you import as a composition/retian layer sizes.
Took 2 days but it was the PSD links in AI the whole time.

One of the possible causes of this error is that you have imported some Illustrator files in your project, and After Effects is having trouble reading them. This happened to me as well when my files were corrupted and were having have complex vector shapes that i used for my client project [1]. Illustrator files are vector graphics, which means they are made of mathematical curves and points, rather than pixels. After Effects can import Illustrator files and convert them into shape layers, which are also vector graphics.
Thanks and Hope it helps too.
