Ready for a strong opinion?
These are children. You are the trained professional with a college degree who is certified to manage all aspects of a classroom.
Might you have one or more students whose behavior is challenging? Absolutely! But is that a reason to blame those children for your classroom community falling apart?
No. Not. Ever.
Just like we individualize instruction to meet the needs of every learner, we must do the same for behavior, especially if you have a student whose behavior is so egregious that it's causing issues within your classroom community.
And you have resources! Your principal and counselor if they are willing (and not all are), as well as other teachers. You can get input on your approach if you go to them with thoughtfulness and not with your hands thrown in the air.
So never do I blame a whole classroom falling apart on the children, and I suspect that your administration feels the same way.
And you know what? “The children” will be there every year. There are teachers in your building who can build communities with the very kids who are currently causing you headaches. Learn and grow and become one of those teachers.
