GPIOB not enabled on STM32WL55JC2

[BNamu.1]

Hello, I just received my WL55JC2 card and I would like to blink one of the leds on the card with a very simple line of code but I don't understand why it doesn't work. I noticed that the led was pinned on the GPIOB which was not enabled in the generation of my code.

Here are some screenshots to help me. Thanks

Hello @BNamu.1 and welcome to the Community :)

First of all, check if the connections, then please make sure to follow this article USB device not recognized, with the solution is to either increase the heap size, or configure the USB library to use static allocation.
