I need help on how to make this not sound like death

I am new to audio editing and to improve my skills, decided to volunteer to edit for someone. However, this is a problem I have never encountered before in my audio. Can anyone tell me what’s wrong?

This is not editing/editorial. This is disaster recovery and I’ve never heard that distortion before.

The distortion is only on the left channel. Discard it , and only use the right channel.
i.e. split stereo track to two mono tracks , then delete the upper (left) track …
