Ensure the GPIO Bank's clock is enabled, configure the specific pins are PP Outputs.

Check for other conflicts and usage.

Check for solder bridges and jumpers.

Many pins with the L072 of the Murata module are committed to internal usage/connectivity.

I've previously posted a long list of these.

Show some code, it'll be easier to unmuddle..

GPIOB->ODR ^= 0x1000;

GPIOB->BSRR = 0x00001000; // PB12 ON

GPIOB->BSRR = 0x10000000; // OFF

Thanks I found the problem, the configuration from STM32Cube did not configure GPIO B bank.
