I WONDER WHY

The issue is shown directly in your log.
“Failed to load audio files: No audio files found in ‘cumming/while’ folder – this is required!”
This means the mod itself is loaded correctly, but the required audio files are missing.
You likely only installed the .dll file and did not include the audio folder/files that come with the mod.
.dll
cumming/while) are placed correctly inside the mod directory
Once the audio files are in the correct location, the mod should work properly.
