FWIW, landlords often include unenforceable terms with respect to lease break fees [1]. This is a common pattern [2].
In my only experience with breaking a lease, my lawyer advised me to inform my landlord that I was aware of California state law, and then wait for them to negotiate. They initially counter-offered that I pay 2.5 months to break the lease, and ultimately agreed to 1 month. Probably harder to do during COVID, though, with such high vacancy rates.
