Lost 30 kg but stuck now – advice for breaking a weight loss plateau?

I used to weigh around 130 kg and recently managed to lose about 30 kg. I'm 6'3" and pretty happy with the progress so far, but now my weight loss has slowed down a lot and it feels like I'm stuck.

I go to the gym regularly and try to stay active, but the scale barely moves anymore. I'm not sure if I need to change my diet, workouts, or just be more patient.

For those who have gone through a weight loss plateau, what helped you start losing again? Any practical tips or things that worked for you would be really appreciated.
