Can I retain muscle if I start running along with my gym workouts?

Recently I’ve started getting into running, really enjoying it so far. But I’m also doing regular gym workouts and don’t want to lose the muscle I’ve built.

If I run a few times a week while keeping my protein intake and training consistent, will I still be able to retain muscle, or should I expect some loss?
Would love to hear what worked for you if you’ve balanced both gym and running.
