As @OlKir1143 said the problem it's with Big Sur 11.3, because my team mates have the same xcode version (12.5) and the problem doesn't exist. I tried everything deleting developer, deleting simulators deleted xcode, everything.

Update to 11.3.1 and it's the same, can anyone confirm? On the first run after the update, xcode requested to install command line tools now i'm having new errors ex: "Class CSAudioFileManager is implemented in both". I know what is this and i didn't had before update. I think the problem it's related to this log: nw_protocol_get_quic_image_block_invoke dlopen libquic failed. Because after this log the app it's launched

Unfortunately i can't find any of the radar's in openRadar or openFeebackAssistant and in the current Feeback Assistant from apple we can't see "Radar's" opened by others. This is mean't to waste our time and duplicate issues or i'm missing something?
