My Minecraft won't get off the Mojang screen. I did everything and nothing is working.

**I don't know what affects verion(s) is so I put a random one I'm sorry. I'm new to all this.

I just need help with my Minecraft. It stays on the loading screen that says Mojang, and I've tried everything I could think of. With COVID-19 quarantine stuff, this is the way I'm communicating with my cousins. Please help me with this as soon as possible. I would take a screenshot, but I can't because my laptop won't allow me. (The camera won't work)
