Microphone overamplified,

I have a ur22mkII interface, cubase pro 11, sure SM58 mic, windows laptop
Synth sounds all work fine.
When I record a voice part the recording is overamplified and distorted although the bar in the mix console is well below 0. This is a new issue, it worked before. Can anyone give me a hand please?

If the signal coming into Cubase is well below zero, yet is still clipping, that means it’s getting clipped (distorted) in the input signal chain, likely at the preamp/interface level. So you should check your gain staging at the audio interface.
