Tools not working at all

I just downloaded onto my Mac. At first it was letting me make shapes with the rectangle tool. But now it’s not letting me even make a shape with the rectangle tool. The pen and pencil tools don’t seem to do anything. I’ve restarted my computer. Does anyone have any ideas

Can you show a screenshot of the window?

Hi Georg. I restarted my computer again for the 2nd time and now it seems to be working. I will post again if I keep seeing issues, sorry about that. Must be my computer.
