I’ve Been Locked Out Of My Bathroom In My Own Apartment

I can’t even use the bathroom. My roommate and I share a Jack-and-Jill bathroom, and both of our bedroom doors and the bathroom doors lock from the inside. Because of this, it was previously impossible for either of us to lock the other person out of the shared bathroom unless we were inside our bedrooms. However, my roommate received permission from the landlord to change the locks on her bedroom door so that she can lock it from the outside. This now allows her to lock me out of both my bedroom and our shared bathroom. She has already used the new lock to prevent me from accessing the bathroom. I texted the landlord about this along with two other concerns. I told him I was being locked out of my bathroom due to the new locks on my roommates bedroom door. He replied saying he will send this to the property manager and it is illegal to prevent me from entering the apartment. The property manager text in the groupchat with all tenants saying that the landlord is not responsible for person conflicts and text the property manager instead. Also that “it is illegal to prevent any tenant from accessing the property. Seek legal authorities if necessary.” I replied to her message stating “Therefore, I should have full access to the front door, my bedroom, and shared bathroom until I have been completely removed from the lease. Is that correct?” And she said “correct”. So my issue is they created a situation that allows my roommate to lock me out of my bathroom which she has done and can lock me out of my bedroom. They have done nothing to resolve this matter. Am I allowed to get an attorney to help me get released from lease without any penalty?
