HELP! MY weight stuck in 64kg, what should i do?i still look skinny but muscular

Eat more.

If you're continuing to lift weights you wont loose your muscle. The only reasons to loose muscle are 1) If you're not eating enough and your body needs to breakdown tissue for energy (a process called gluconeogenesis) and 2) If you stop working out, because your body has no reason to keep muscle that its not using. Muscle is "expensive" in terms of caloric needs so the body will only keep it if there are enough calories. Hope it helps.

Are you lifting with progressive overload?
You only lose muscle if you calorie deficit hard and DON'T use your muscles. It's called atrophy.
