    Dear @Kévin,

    Thank you for reaching out to Microsoft Q&A forum.

    I understand that you’re experiencing an unexpected issue with Power Query. From my research, this issue means that your Power Query "Container" is crashing because of a compatibility issue between the Snapdragon X Elite (ARM64) architecture and the emulated x64 background processes that Power Query uses to preview data.

    The error code 0xC000026F specifically refers to an internal failure in the Win32 emulation subsystem. Since Power Query launches a separate process to handle data, this "container" is failing to bridge the gap between your ARM64 processor and the standard Intel/AMD (x64) code that Power Query still relies on. To ensure you receive the most accurate and specialized guidance, I recommend posting your query on the Microsoft Power Platform Community Forum Thread

    User's image

    That forum is dedicated to Power Platform and supported by a knowledgeable community, including Microsoft experts and partners. By posting there, you’ll gain access to deeper expertise and resources that can help resolve this issue more effectively.

    I apologize for redirecting you to a different community, but this step will connect you with the right specialists. We are willing to help you, but we are concerned about providing incorrect information that may not benefit you. We sincerely hope you can find a perfect solution with the support of experienced specialists and community members. We also welcome any community members to share their ideas about your situation if they have related experiences.

    Additionally, I recommend that the Global Admin in your organization create a service request with Microsoft Support. A technical support engineer can perform a remote session to investigate the situation, verify the backend configurations, and run any necessary synchronization tools to resolve the problem. If the issue requires further attention, they can escalate it to a specialized team for deeper analysis. Ask The Global Admin in your organization to create a service request with Microsoft support to get advanced technical assistance and diagnostics. For detailed instructions on how to get support, please refer to Get support - Microsoft 365 admin. If you don't know who your IT administrator is, please refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support 

    For additional assistance, use this link to find the appropriate contact number from your region: Global Customer Service phone numbers - Microsoft Support 

    I know this isn't the answer you were hoping for, and it's disappointing when the solutions aren't straightforward. Please know that as a forum moderator, directing you to the correct, specialized support is the most effective help I can provide from my position. I truly hope you get your issue resolved swiftly. I wish you all the best. 

    May the New Year bring happiness and success to you and your family.

    The error code 0xC000026F indicates that the container unexpectedly exited while running Power Query. This can occur due to various reasons, including issues with the Power Query environment, compatibility problems, or resource limitations on your system. Here are some steps you can take to troubleshoot the issue:

    1. Check System Requirements: Ensure that your system meets the requirements for running Power Query, especially since you are using an ARM-based processor.
    2. Update Power Query: Make sure you are using the latest version of Power Query. Updates often include bug fixes and improvements that can resolve unexpected errors.
    3. Check for Conflicting Software: Sometimes, other applications or services running on your system can conflict with Power Query. Try closing unnecessary applications and see if the issue persists.
    4. Reinstall Power Query: If the problem continues, consider reinstalling Power Query to ensure that all components are correctly installed and configured.
    5. Review Resource Usage: Since your system has 32 GB of RAM, ensure that there are no resource constraints. Check the Task Manager to see if Power Query is consuming excessive resources or if there are other processes that are using a lot of memory.
    6. Check for Corrupt Files: If the error occurs with specific files, those files may be corrupted. Try using different files to see if the issue is consistent.
    7. Consult Logs: If available, check the logs for more detailed error messages that might provide further insight into what is causing the container to exit unexpectedly.

    If none of these steps resolve the issue, you may want to reach out to Microsoft support for further assistance, as they can provide more tailored troubleshooting based on your specific environment and error details.
