Problem exporting to MP3

When I export to MP3, Cubase 11 saves it as a Win Media file that doesn’t play in Win Media.
Can someone help with this.

Hi,
Could you attach the Export Audio Mixdown window screenshot, please?

The MP3 file is marked as MPEG 3.

No definitely not.
If no mp3 file handler is present, Windows says it’s Windows Media even if it’s .mp3.
