Degradation of UDP communication performance depending on STM32Cube FW H7 version (v1.11.1 to v1.11.2)

In STM32Cube FW_H7 version 1.11.1, UDP performance was normal, but in version 1.11.2, it fails to handle all transmitted and received packets. (STM32CubeMX Version 6.12.0)

Except for the STM32Cube H7 firmware version, all configurations and source code are identical.

The configuration (without RTOS) of my project is below.

How do I fix this? Should I use version 1.11.1 temporarily? Or will this issue be fixed in the future?
