Slideshow Classic won't import music: file not well formed

Im getting the same message. If you can't upload music in lightroom for the slideshow presentations, what's the use in it? Please get back to us on the answer. 

I too am having these issues, version 9.2 release.  

Have been on 3 calls with technical support, then a scheduled call for over two hours, and case hase been escalated to higher support unit.  

Waiting over 7 days and not heard anything.   Checked today, was told, they will get to me when they can....

Worked on previous builds.... not sure updating was really worth it..

Frustrating... 

Hi there,

That's not a typical experience with Lightroom Classic as you're getting an error "music file not well formed", let help make this right.

Would you mind restoring Lightroom Classic app preferences to default and let us know if the issue still persists? Please refer this article for step by step instructions:
