When i have select PB11 PA7 and PA5 has GPIO_OUTPUT it is giving issue in flashing program
Please tell me solution

GPIO configuration is done by your code, after reset, typically in main(). So GPIO settings shouldn't matter for flashing. Use STM32CubeProgrammer for flashing, it has variuos options like connecting under reset at different speeds.

Your question is missing details: What is connected to the outputs or other pins? Boot mode (pins and option bytes)? Is the flash empty or was it programmed before? Known good hardware or new/own design? ...

Please see How to write your question to maximize your chance... - STMicroelectronics Community

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
