When trying to launch VsCode from launcher or terminal it's not launching. On code --verbose command it's showing the following error

Error: ENOSPC: no space left on device, watch '/snap/code'

Os- Ubuntu 18.04(64bit)

I am trying to find my 5Ghz ssid and then I will try to connect it but it's not showing up.
