STM32 MAT-TARGET is not working with Matlab 2020b

I was using Stm32 Mat-Target with the Matlab 2018b version without any problem, but I could not run it with the 2020b version. Is it compatible with 2020b? When I compile the Simulink model, I get an error message as below. The problem seems to be related to Java software. Can anyone suggest a solution for this problem?

• Operating system is Win7 Ultimate
• CubeMX version 5.6.1
• Java version 8 update 281 (build 1.8.0_281-b09)

The issue has been resolved as a result of some updates. However, I am not sure what the problem was. The working configuration is as follows;

• Operating system is Win7 Ultimate
• Matlab 2020b
• CubeMX 6.2.0
• STM32-MAT/TARGET 5.6.0
• Keil uVision V5.29.0.0
