Oof, hope you win more games
Can't stay above 1100
I would try to see if there is a common theme and then start deeply thinking about an opening strategy you can use

Take a second and think about If a week of beeing 1100+ and then dropping down to 1000 and beeing "stuck", could really be considered "beeing stuck".. I mean, for real.. If you think you will climb another 100 ratings per week, you soon realize that you will become the highest rated player of all time, before the year end. Just keep grinding bro.

First thing you have to do in order to stay above 1100 is learning opening principles. What I mean by that is not learning certain openings, but learning how to play in the opening. Fight for the centre/ develop pieces towards the centre/ don t move the same piece twice/ castle/ connect your rooks. Next try to improve your tactic skill. Solve at least 4-5 puzzles a day. An most important, when you play you should be focused at the game itself so your brain helps you to come up with good ideas/moves.

I play daily puzzles everyday and got a 180+ streak but I lost it, after playing daily puzzles I usually do the puzzles or puzzle rush and puzzle battle, thtat should equal to 4 or more puzzles

Maybe try learning the openings that your opponents played? For example, if you're black and white plays King's Fianchetto or King's Gambit or other fancy opening, you could try to study the opening and find a huge advantage.
