Issues with Trust Ermita microphone

Calling for help…
I’m new to recording. I just started using my new Trust Ermita USB microphone and the recording sounds awful.
It’s echo-ey, there’s a kind of feedback alieney effect - feedback? - and there’s “noise” around the voice. No clarity.
I don’t know if there’s something wrong with the microphone, or the cable, or if I’ve just set it up wrong.
I can’t find much info online about this mike.
Any suggestions would be most welcome, and it’s fairly urgent.
