STM32F0 EXTI Port unusable

Hello,

I noticed a problem with the STM32F030F4P6 Microcontroller.

When I configure EXTI Line 0 and 1 with GPIOF =>

PF0,PF1 are my EXTI for two Light Fork Barrier Modules.

then all of the sudden my PB1 Pin can't be toggled(and yes I initialized it).

Is this a known issue that EXTI Line 1 Config disables other Port Pins with 1?

(For Example PA1,PB1,PC1 ect.)

I can upload code example if needed.

Thanks.

Disable interrupts.

Still can't toggle PB1?
