UR 22 Audio feedback loop-Help!

Hi Amat7 Yes its very similar to a CD stuttering-it last for about 3-4 repeats and then its stops. Its been going on for about a year now-very intermittent some days its there other days its not however I have to say I am still on Mojave. I have put in a support message to my Steinberg account but that was weeks ago-the virus probably having a lot to do with the lack of response. Im presuming its something to do with a clash of audio drivers but I only have the UR22. I did try down grading the UR22 driver but that did nothing. also getting rid of sound flower but still no good. I’m on my computer today but so far it hasn’t happened! Its very frustrating!
