MOODE AUDIO

Hello
I'm just trying this new player but I can't make it work.
I'm using one RPI4 with ES9038 hat and one USB flash drive with 300 DFF files.
After configuration and reboot, the configuring window is frozen, the library shows radio stations but I can't see anywhere my music folders.
Where is the error ?
Until now, I was using Volumio and it' works great with one exception : there is a random POP when changing track.
So I wanted to give Moode a try.
