Steps to Reproduce

I encountered a crash when using the experimental Metrics feature. I use this feature to log the duration of a request. This block of code is sent from a background thread each time a response is received from the server:

SentrySDK.metrics.distribution(
        key: "http.requests.durations",
        value: duration,
        unit: MeasurementUnitDuration.second,
        tags: [
          "request.template": requestTemplate,
          "status": "\(dataResponse.status.code)",
          "locale": Locale.current.identifier
        ]
      )

The crash is intermittent and quite difficult to reproduce. Crash logs:

EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000154
