I did the command by accident whilst trying to fix things not being able to upload files anywhere and now some of my software is refusing to open, including the software centre itself, I'm newish to Ubuntu so I'm not super sure of what I'm doing, definitely learning by my mistakes a bit

Doing what you did has effectively has broken your system in an irreparable way. Given that you admittedly are 'newish' to Ubuntu, then you'll have to reinstall to fix the permissions. (To fix the permissions manually will be a days-on-end process and will take a LOT more knowledge than you have about Ubuntu, and it is effectively faster for you to reinstall than try to fix the issue.)
NEVER run recursive chmod on the root - it's basically making your life hell, and on this site there's no way to restore your system to working without a reinstall.
And unless you really understand what a command does, don't randomly execute commands with sudo access.
