MSP430F5419A: Question about BSL and program start address

In BSL, the program start address does not work.

Condition:
mcu: msp430F5419A,
I used BSL scripter. (3.1.0.0)
It uses the IAR compiler.
I used rocket BSL and downloaded A_app.txt and B_app.txt.

situation:
Even if SET_PC is performed with the program start address in BSL,
It does not jump to the original program position.

After BSL execution of A_app.txt file, if SET_PC is set to reset vector 0xFFFE, A_app.txt program restarts the program.
After executing BSL of B_app.txt file, if SET_PC is set to reset vector 0xFFFE, B_app.txt program does not restart program.

Even if SET_PC is set as the program start address, normal program start is not performed for the B_app.txt program.

Question 1: After the bootloader operation is finished by performing set_PC as a reset vector in BSL
Can you make it reset? Disconnecting power is not considered.

Question 2: In BSL, by doing set_PC with the program address,
Can you make it a normal program? Disconnecting power is not considered.

Thanks for reading the question.
