Examine TypeError: Cannot read properties of null (reading 'useContext') in stdout.

We found this behaviour in our canary tests for new Next.js versions for the Sentry Next.js SDK from version [email protected] (could be earlier, it was just the first canary test we noticed it on).

The repro app doesn't really do anything besides throwing inside middleware.

Good part: This behaviour only happens when the application state is already panicking. Bad part: It appears to affect the Sentry SDK, which does a bunch of stuff when errors happen.
