Don't you miscalculate page number? Btw. check return codes, on FLASH operations they are critical.
Try the demo in CubeMx repository:
STM32Cube\Repository\STM32Cube_FW_L4_V1.13.0RC3\Projects\NUCLEO-L476RG\Examples\FLASH\FLASH_EraseProgram\
2018-09-12 02:56 PM
status = HAL_FLASH_Program(FLASH_TYPEPROGRAM_DOUBLEWORD,0x0807F802,((uint64_t)data_1 << 32) | data_2);
You can't write to unaligned addresses, writing 64-bit, be 8-byte aligned, for 32-bit be 4-byte aligned.
0x0807F802 clearly not suitable for 32-bit or 64-bit access
