Personally I'd try a diet break and going back to maintenance calories.
Last summer I set myself a target of 70kg from about 74kg, just for holidays. I upped my gym work to 7 days a week from 4-5 and added around 40-60 minutes walking per day. Lost a couple of kilos but didn't get to 70kg.
Same after Christmas. Lost the holiday fat during January, with diet and weights. Then basically plateaued through February, despite adding in walking and calisthenics core exercises daily.
So for March I'm eating maintenance calories and not getting on the scales or measuring myself.
I have to say I don't think I've gained any weight judging by my clothes fit, may have even lost a couple of inches. I'd also say I have far more energy during weight training sessions, than at anytime in the last six months.
Although I say I'm eating maintenance calories, some days I just can't get there, without ditching my macros. But weekends are more relaxed and so I generally go over maintenance and stay chilled out over the macros. But still eat the required protein for the day.
