All Settings lost after new session

Hi, I am using a MacBook Pro with System 15.1.1 and Shotcut version 24.11.17.
Every time I close and reopen Shotcut, the settings, such as the filter favourites in the list, are gone or reset to the default favourites. The complete layout, as I prefer it, is also overwritten. Are there perhaps special files to delete for this problem?

Kind regards, Gottfried

The config file location is explained in the FAQ in the web site as well as the documentation.
