Analysis

The repair specified here probably removes the unknown type, referring to the error message. The newly created file is only a tens of bytes smaller than the original.

Is it a bug in the validating software? -

Possible solutions

Recreate WAV file with single audio stream and metadata

The suggestion

Copy the first audio stream and ‘global metadata’ of the stream 0 to a new file.

Execution

ffmpeg -i <input file>.WAV -vn -c:a copy -map_metadata 0 <output file>.WAV

Tested with: FFmpeg 6.0

Effects

Only the first audio stream in the file is copied from the input file to the output file. Video streams are explicitly excluded with -vn from the migration.

Justification

Only audio stream and metadata needs to be migrated.
