Warning: This will remove all users from your chromebook. I'm not sure what else it does because I have never done this. However, I do know that lots of your things are saved on your user account. When I got a new chromebook because the old one got water damage, I set up my user account and there was all my browser history and bookmarks! However, I do remember needing to reinstall browser extensions (which shouldn't be a problem), and I'm not sure if it saves your files, so best to backup your files on somewhere like Google Drive just to be safe. I'm also not sure if this will solve your freezing problem, so maybe try going to chromebook help.
I haven't used this so I'm not sure if it has the answer to your problem, but search around and you may find a solution. Good luck!
Edit: I looked around a bit and found something that might help. It said this:
Try rebooting the device. Hold down the power button until the device has completely shut down, and then turn on the device again.
