Unexpected property handle(s) customizing FSoundAttenuationSettings. Error: Ensure condition failed.

UE 5.0.3
When I try to select my Ambient Sound object in UE editor, I takes errors (on the picture)
Why this is happening? This is UE’s bug?


And, somebody, set up this question ‘editor-crash’ tag, I cannot choose that.

The error is gone. For this I regenerated project (for this I deleted files: (saved, intermediate, binaries, .vs) and launched “Generate VS project files”).

I tried these recommendations and much more. None worked.

What did finally stop this error for me was deleting all folders that start with “Unreal” in %localappdata%

For reference I also did a Clean / Rebuild in Visual Studio and I did a “Verify” on Unreal Engine… and started disabling Sound / Audio plugins and code within my project (since this seems audio related?)… but these did not seem to help.

+1 this, worked for me too
Skipped deleting saved folder in project though, fix was appdata files
