Request for File Recovery – Animation layers flattened and converted to PSD

Hello, I am experiencing a critical bug where my Fresco animation files are being automatically converted into PSD format and all animation layers/frames are flattened into a single non-editable layer.  Could you please investigate if there is any way to restore a previous version from the server-side that still retains the original Fresco animation structure? I have already checked the Version History on my device, but the error seems to have synced across all versions.
