Video file not recognised as video but as audio

When I imported the video clip (MP4) into Premiere Elements 2018, it's not recognised as a video file but as audio file. When I used VLC to open the file outside of Premiere Elements it plays as a video file without any problem. I am using Windows 10. What is happening and how can I import it as a video file? I am able to import other video files without any problems, it is just the particular one.
