The program automatically cycles through a number of web-streams from internet radio (in the real application the user presses buttons to switch stations). After a few URLs, the Pico2W just disconnects and needs a hard reset for a restart. Behavior is random, sometime it fails after three streams, sometimes later.Switching streams seems to be the problem, playing a single stream for an extended time works without problems for all of the example URLs.
Note that you don't need real I2S hardware to reproduce the error. Also, the program works fine on an ESP32-S3.
Some speculations: maybe the network-stack of the Pico2W does not cleanup resources and fails after a while. Or it produces illegal data during close and this trips the MP3Decoder.
