    Hi,

    Thank you for posting your concern. The dxva2.dll error is referring to DirectX Video Acceleration 2.0 DLL that is required by some applications to run properly. To help you better with this, we would like to confirm some specific information about your computer. Please answer the following questions:

    • When did this issue start?
    • What specific application did you run before getting the error?
    • Have you made any changes to your computer prior this concern?

    Meanwhile, you can perform the following troubleshooting steps:

    Make sure that Windows is up-to-date

    1. Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings. (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, click Settings, and then click Change PC settings.)
    2. Tap or click Update and recovery, and then tap or click Windows Update.
    3. Tap or click Check now.
    4. If updates are found, tap or click View details and choose Install.

    If the same issue persists, please head over to this link and download DirectX Video Acceleration Specification for High Efficiency Video Coding (HEVC).

    We'll be waiting for your response and the result.
