I am unable to start my MacBook, it’s stuck on which screen. those screenshots are attached pls do help.

Not sure if you're aware but those images indicate how to turn the power on in a Magic Mouse and a Magic Keyboard. That is something that can happen if your internet keyboard and trackpad aren't working.

If you've tried restarting and are getting the same thing, you may want to contact Apple Support to see if they can help: Contact - Official Apple Support
