failed to import ddtrace module 'ddtrace.contrib.langchain' when patching on import

Summary of problem

We started getting an error with DDTrace described in the title. We used to have langchain pinned because this was an issue before as well. Since then though we don't have it pinned any longer.

How can we reproduce your problem?

I wish I could figure out what's actually causing this, but I'm having trouble figuring out where this is even being triggered from.
