Avoid .unwrap() on cache access (#5229)

Browse source 
## Summary

I haven't been able to determine why / when this is happening, but in
some cases, users are reporting that this `unwrap()` is causing a panic.
It's fine to just return `None` here and fallback to "No cache",
certainly better than panicking (while we figure out the edge case).

Closes #5225.

Closes #5228.
