Answer 1

I had the same problem, and it was related to what @goku_da_master commented, I had the vueJs application running even when my VsCode stopped, I figured it out from the task manager and fixed it like this:

• I opened the task manager
• I searched if Node.js was running
• Right click on the Node.js process
• Finish Task
• "npm run dev" again
