It seems like you might be experiencing issues with the Go extension for Visual Studio Code or possibly some conflicting extensions. Let’s try a few steps to troubleshoot and resolve the issue:

1. Update the Go extension: Ensure that you have the latest version of the Go extension installed. You can update it by going to the Extensions view (Ctrl+Shift+X), searching for “Go,” and clicking on the “Update” button if it’s available.

2. Restart Visual Studio Code: After updating the extension, restart Visual Studio Code to apply any changes.

3. Check for conflicting extensions: Disable other extensions that might conflict with the Go extension. Temporarily disable extensions, restart VS Code, and see if the issue persists. If it doesn’t, re-enable each extension one by one to identify the conflicting extension.

4. Check for syntax errors in your Go environment: Ensure that your Go environment is set up correctly. Open a terminal and run go version to check if Go is installed and properly configured. Additionally, try running a simple Go program outside VS Code to verify that there are no syntax errors.

5. Check VS Code settings: Open your VS Code settings (Ctrl+,) and search for “format on save” and “format on type.” Ensure that these settings are set appropriately for Go. For example, you might want to set "editor.formatOnSave": true for automatic formatting.

6. Check for Go-related errors in the Output panel: Open the Output panel in VS Code (Ctrl+Backtick or View > Output) and select “Go.” Look for any error messages or warnings related to the Go extension.

7. Reinstall the Go extension: If the issue persists, try reinstalling the Go extension. Uninstall it from the Extensions view, restart VS Code, and then install it again.

8. Check Go tools installation: Ensure that the necessary Go tools (gopls, goimports, etc.) are installed. You can install them by running the following commands in your terminal:

go get golang.org/x/tools/gopls go get golang.org/x/tools/cmd/goimports

Make sure that the directories where these tools are installed are included in your system’s PATH.

1. Verify workspace settings: Open the .vscode/settings.json file in your project and check if there are any custom settings that might be affecting the behavior. Resetting settings to default might also help.

If after trying these steps, the issue persists, you might want to seek assistance on the official Go extension repository on GitHub or the Visual Studio Code GitHub repository. They can provide more specific guidance and help you resolve any potential bugs or conflicts.
