TL;DR:

The 0xc00d5212 error occurs when Windows Media Player lacks the specific software codecs required to decode an AVI file on Windows 10, which can typically be resolved by enabling automatic codec downloads, fixing driver conflicts, or switching to a natively compatible player like VLC Media Player.
    ● Force Windows Media Player to install missing codecs by navigating to Tools > Options > Player, setting Automatic updates to "Once a day," and reopening the AVI file to trigger the download prompt.
    ● Resolve system conflicts by opening Device Manager to update or reinstall your display adapters, and uninstall any multiple overlapping audio drivers that may disrupt media playback.
    ● If the error persists after software updates, the AVI file itself is likely corrupted and requires a dedicated recovery tool like Wondershare Repairit to rebuild the file using a healthy sample video generated from the same device.
