Help removing feedback please

Hello all. I would appreciate any advice you have on improving this audio clip.

I’m using a usb condenser mic with pop filter and running it though audacity.

I’ve used noise reduction to remove background feedback but I’m also getting feedback on my voice.

Do you know why this is happening or how to edit it out please?

Thankyou for your input

Thankyou Trebor. Some great suggestions to try

It can be notched out …

But prevention is better than cure: the notch causes collateral damage.
