File korrupt from Teddy cli

Hi, I am trying to use the command Line tool teddy from the GitHub repo to convert mp3 to a Tonie File. But when trying to let the File running ob the Toniebox it does nit Work. Led blinks red and The Box shuts down. When Decoding the File which was created with my mp3 I get “File corrupt”

Any Idea whs IT does not Work with Teddy?

O tried to run Teddybench, but gut Errors when building with dotnet build

You could try to use the prebuild teddybench from the releases:
