@cryptic.ax issue with the new MTK v10? We should allow this as an alternative steady state definition.

But for now, removing the t-dependence is fine.

    para = @parameters begin
        p
    end

    end
    eqs = [
        x^2 ~ y^2 - p^2,
    ]
    return System(eqs,vars,para,name=name)
end

@named sys = my_func()
sys_ = mtkcompile(sys,fully_determined = false)

using NonlinearSolve
prob = NonlinearLeastSquaresProblem(sys_,[sys_.y => 1.0,sys_.x => 0, sys_.p => 2])
sol = solve(prob)
