Thank you for your answer!
This might be the case, if so theres nothing I can do.
But when I tried to play the m3u8 using https://github.com/schreibfaul1/ESP32-vs1053_ext,
I got the following error:

I wonder if it has something to do with the missing PSRAM.
Because the station I tried to stream is in the actual example of the Git Repository, so it should work
