since yesterday, the backtest build and buttons disappear upon loading a project. They are visible for 2 seconds (greyed out) and then the disappear. Reloading the project does not help.

Here are some steps and considerations to help resolve the issue of disappearing backtest buttons in QuantConnect when using VS Code:
Browser and Cache: Since the issue involves the web interface, ensure your browser cache is cleared. This can sometimes resolve UI-related issues.
Browser Compatibility: Make sure you are using a supported browser version. QuantConnect may have specific requirements for browser compatibility.
Disable Extensions: Temporarily disable any browser extensions that might interfere with the QuantConnect interface, such as ad blockers or script blockers.
Console Errors: Check the browser's developer console for any JavaScript errors or network issues that might be causing the buttons to disappear.
Different Browser: Try accessing QuantConnect using a different browser to see if the issue is browser-specific.
VS Code Extensions: Ensure that you have the necessary extensions installed in VS Code for Python development, such as the Python and Pylance extensions. These are crucial for proper functionality and integration.
QuantConnect CLI: If you are using the Lean CLI for local development, ensure it is properly configured for your environment. This includes setting up local autocomplete and ensuring all dependencies are correctly installed.
Contact Support: If the issue persists, consider reaching out to QuantConnect support with details of the problem, including any error messages from the console and steps already taken.
