Status bar disappears automatically

im using realme 12 pro plus and I'm using niagra launcher pro. when i use my phone after restart the status bar is completely fine but when i go to my recent apps that's running in my background and choose a app or came back to my home screen the status bar disappears automatically idk why it's happening i did everything i could changed settings and it didn't help i think it should be a bug also when i use nova launcher it shows the same problem it's only fine when i use system launcher that is realme ui 6 please solve this issue because i love niagra launcher but this issue makes me not to use this launcher. thank you.
