Literally just did it. Press the green button, app goes full screen, other two monitors turn black. Same thing happens when someone starts screensharing with zoom and it goes full screen.
Is it the application you’re using?
Something bugged on your system?
Is it an older system where maybe that was a shortcoming?
I pulled up my Mac which I use to use with multiple monitors many times and tested again to ensure I wasn’t crazy and nope. I can have two different full screen apps open at the same time, one on each monitor.
Or a full screen on one, and the other just showing windowed applications with my dock visible.
That is not how full screen works on Mac. Why are you asserting something demonstrably false?
