Do you have disabled in the render-dialog -> more options -> parallel processing? If not do so and try again.

Thank you for the feedback and contribution. Glad to hear it works. Parallel processing is now disabled by default. We close this bug. If it still appears in the latest version, please feel free to re-open it and update the affected version number.
