how can i fix the code editor ?

Hi LEUL MERID,

Thank you for reaching out to Microsoft Q & A forum.   

I'm sorry to hear that the .NET Code Editor isn't loading for you. Here are a few things you can try to fix the issue: 

1.Clear Your Browser Cache: Sometimes, old cache data can cause the editor to misbehave. Clearing your browser's cache and cookies may resolve the problem. 

2.Try a Different Browser or Device: If possible, try opening the course in a different web browser (like Chrome, Edge, or Firefox) or on another device. 

3.Disable Browser Extensions: Some browser extensions (like ad blockers) may interfere with the editor. Try disabling them temporarily. 

4.Check Internet Connection: Ensure your internet connection is stable. A slow or unstable connection might cause the editor to load indefinitely. 

5.Update Your Browser: Make sure you're using the latest version of your browser, as older versions might not fully support the .NET Editor. 

Please feel free to contact us if you have any additional questions.
