Unable to import audio files.

[TheGaming999]

Version: 3.3.0.8617-preview Tested affected versions: 3.2.0.7787-preview

Steps to reproduce:

• Create a new project
• Import an asset that is an audio file. In my case, I imported an MP3 file.

Expected behavior:

• Being able to play the sound file and import it without any error logs.

What really happend:

• I couldn't play the audio file and I got an error with following message:

  Error exporting E:/Projects/WaveEngine Projects/MyWaveProject/Content/Scenes/BGM_Christmas.MP3.wesn.

Weird fix, but it works. Just open the audio file in AudaCity and export again without changing anything.
