Run after the programming option doesn't work

[HKaze.1]

I'm using STMCubeProgrammer for program STM32F103 MCU. But I don't have any access to MCU RESET PIN. So I enter to BOOT Mode by source code in my application, But when I want to turn back to application from boot mode the "Run After Programming" option doesn't work correctly.

How can I turn back to application from boot mode without access to reset Pin?

Thanks.

Bootloaders knows a "go <address>" command. But why not reset the MCU programmatically? To make option byte setting actiive, either option byte reload or reset is needed anyways.
