Why Does My Cache File Contain an Audio Section?

When I try to render my project, it crashes on certain Fusion compositions. As a workaround, I have been rendering those portions of the project, and then selecting "use rendered cache images" (paraphrasing) on the Delivery section. However, I've noticed that the cache location where Resolve caches my project files also has an "audio" section, which concerns me that the audio is also being cached. Is this normal? I'm trying to avoid using rendered cache files for the final output unless it is absolutely necessary (e.g., the Fusion clips), so I don't want the final output to use pre-rendered audio (as opposed to rendering it natively as part of the final render process).

Is there a way to disable rendering of audio, or if not, is there any harm in deleting the "audio" file that is within the main Cache file?

That location is where audio waveforms are stored. If you look at the files, you'll see they're quite small -- assuming you're not actively caching audio tracks. Just leave the files alone. You can delete them, but they'll grow back as needed.

Ok, thank you for the breakdown!
