Steps to Reproduce

These errors seem to have begun at the beginning of August, after the following PR landed:
#2493

They fire intermittently as the result of cross-api backend calls where we are forwarding sentry headers along to another request (for distributed tracing). As a result I don't have a consistent repro. Mainly I would like a way to disable these from throwing until a resolution can be found, but since this is an exception coming from Sentry internals I'm not sure how best to avoid it.

It appears this functionality is tied to Dynamic Sampling so I assumed that disabling Performance tracing would prevent the issue. But it appears that you can't disable backend/API performance tracing if it is enabled on an incoming request from a frontend client that has it enabled (for distributed tracing).

Expected Result

No exception thrown (possibly a logged error instead?)

Actual Result

Sorry about that. The SDK definitely should not just throw. Fix is coming asap.
