Photoshop will not let me draw

Hello, whenever I try to draw no marks on the canvas will appear. I have made sure that I have:

No marquee areas I forget about,

That my opacity isn't to low, or the same color as my canvas,

I have reset my tools,

my photoshop is update to date so is my windows, 

I have a Wacom Intuos S 2018 version if that means anything,

made sure the brush mode is normal,

that covers everything that I can think of aside from resetting preferences, but I don't want to keep resetting preferences every time this happens. Any help would be greatly appreciated, as this issue is very annoying.
