Can not share screen

Hello, I am using zoom version 5.15.11, so I can not share the screen in a meeting when I pulse "Share screen" option appears a window with only 3 options:

- Use system desktop capture

- Use system window capture

- Whiteboard

I chose the first and the second one but do not work. I review the share options in the app and is active, I don't know what can be happen.

Thanks in advanced
