STM32F746G-DISCO screen goes blank when generating PWM signals

Hello everyone! I have been trying to do a project where I try to control a PWM signal with the touchscreen I made with TouchGFX on my STM32F746G-DISCO, unfortunately, after generating a PWM signal, the screen just goes blank, it doesn't turn off, it just goes completely white. I tried different TIM pins, different configurations and different duty cycles.

Is there something I'm missing? I need to generate at least 2-3 PWM signals and if I am unable to do it with this then I have to use something completely different, I am new to all this so I don't know as much, I can give more information as neccesary!
