Project for reproducing the bug

SUMMARY
Attempting to use an audio effect, such as Dialoguenhance, causes an "Unexpected return format" error with the effect not working.

I've tested the folllowing effects and they do not work, showing an error message:

- Dialoguenhance
- Speechnorm

STEPS TO REPRODUCE
1. Use the effect on a video clip with audio
2. Start playback

OBSERVED RESULT
A small error window pops up in the "Effect/Composition Stack" panel, saying "[filter avfilter.dialoguenhance] Unexpected return format". The title of the error window says "Dialoguenhance". (See attached screenshot.)

The effect also does not have any effect on the clip.

EXPECTED RESULT
The effect works on the clip.

SOFTWARE/OS VERSIONS
Windows: 11, Version 23H2 (OS Build 22631.3737)

ADDITIONAL INFORMATION
I've attached a demo project with the associated clip.
