Ok here is the thing, when you do a trace route to an IP address, regardless if it’s valid or not the device will try to find the IP address. This finding will only stop once it reaches it’s 30 hops.
Normal case in command prompt you could stop this by doing CTRL+C or CTRL+break.
But in Cisco Devices you can only stop this by doing CTRL+SHIFT+6 which is one of the break sequence on Cisco devices.
Small things helps when you are frustrated!
