Accidentally typed node . instead of code . to open VS Code via WSL and it's not opening VS Code now

I accidentally typed node . instead of code . to open VS Code via WSL and when I typed code . again it will not open VS Code no more. Does anyone know how I can fix this? After typing code . normally it will return a new line for you to type command in and also open VS code, and now it's just showing the user@LAPTOP-xxxxx:~$ to get you to type in command. Please help, thanks.
