I’m assuming that you are using Squeezelite, this behaviour has been reported in the Slimproto forum, you could check over there searching for the Muse Luxe thread.
But try to open a serial terminal, you should still have the command prompt and you can try to go in recovery mode :
nvs_erase_wifi_manager
restart
What I think is happening is that Squeezelite have a hard reset while it is writing some config data, resulting in some data corruption.
