my macbook air wont force quit apps or shut down

Hi everyone! So yesterday my teams was being weird and I couldn’t open it unless someone sent a message and I clicked on it. Finished what I needed to do and tried to restart it, wouldn’t do anything. Then force quit apps, again, nothing happened. I then tried to shut it down and nothing! It’s as though I’m clicking on the actions and they don’t exist or something :/ v worried pls help!!
