Soundcore 2 error make strange sound

I have an unusual glitch with my soundcore.
When I press the volume-up button, instead of increasing the volume, the soundcore will make a ‘version zero five four’ sound and then disconnect and make another sound like a warning sound. And when I try to reconnect my phone it will ask me to forget the device.

I have tried to do a hard reset by pressing the power button for 8 seconds but it doesn’t work.

What should I do?
