Seems like your main needs to be named the same as the folder name, like you are running the ide in "arduino" folder, the main file should be name arduino.ino
Arduino expects the main file of the project to have the same name as the folder in which it is saved. Here's how you should adjust the structure: If your project folder is named vscode_example, the main file should be named vscode_example.ino. Make sure that the .ino file is in the root directory of the project folder.
Output path is not specified
Error opening sketch: no valid sketch found
