by the way, I have a main 240hz monitor and a secondary 60hz monitor, I don't know if this could be related or not... but the crash happens even with the secondary monitor turned off

I have updated the graphics card driver to the latest version (other drivers are already up to date) and checked the installation files integrity through Steam (using the delete saved configs option)
After that I could enable the Hardware Antialiasing, but that made me realize the crash is related to de Fullscreed/Windowed mode.
