Unknown app preventing restart

Today I tried to restart and update my laptop but there was an app called "cptmsg" preventing it from restarting. I tried googling what it is but nothing seems to explain what this is

I could also add that I wanted to restart my laptop because my WiFi suddenly stopped working on my laptop and my chrome tabs mentioned something about the a firewall. I'm not sure if this info is relevant or not. Once I restarted my WiFi started to work again.

What exactly is the app and what does it do? Is it something harmful to my laptop
