Non-radial Blow-up for a mass-critical fourth-order inhomogeneous nonlinear Schr\"odinger equation

We investigate the blow-up for fourth-order Schr\"odinger equation with a mas-critical focusing inhomogeneous nonliniearity. We prove the finite/infinite time blow-up of non-radial solutions with negative energy. Our result serves as a valuable complement to the existing literature, offering an improvement in our understanding of the subject matter.
