Doing high intensity cardio won't make you lose muscle. People usually lose muscle when doing way too much cardio overall - eg. 1 hour per day running or more.
HIIT (high intensity interval training) actually raises your BMR for the next 24 hours, so the net benefit is higher than the slower cardio. This is why I usually suggest 2 sessions of 20 min HIIT + 1-2 longer slower sessions (assuming no health problems prevent the HIIT) weekly.
I wouldn't worry about losing muscle as long as you don't do fasted cardio.
