Does anyone know the way to fix compile button gray out error in unreal engine 5?

When you mean compile you mean play level button?
Do you have a level loaded? has something gone wrong loading it?

Hi, I have a couple of things that might help:

  1. Restart Unreal Engine
  2. Use the shortcut keys such as ALT + S OR ALT + P (assuming your on windows)
  3. Save all your files, then reload the level

Hope this was able to help. :+1:
