I'm having issues with desktop app Supersonic which is connecting to my nextcloud and works most of it like album,artists etc. and only crashes when i want to get all tracks. I already talked with dev of Supersonic and he made some kind of failsafe for it but still doesn't find any problem on his side but more likely of this app.
Supersonic github: https://github.com/dweymouth/supersonic
Also attaching the screenshot of error.
