I need to figure out why my mic isn’t picking up any sound

Hi there! I'm looking for someone to help me figure out why my XLR microphone isn't picking up sound on all applications. I've already checked the audio settings, and they seem to be in order. I'm hoping to find someone experienced with this kind of issue to identify the root cause and advise on the best course of action. If you think you can help me, please reach out. Thanks!
