Unreal Craches when i press play button

Unreal crach when I press play button , I don’t know what to do please help

Close and reopen unreal.
Click the “build” button.

Check your level blueprint, or any other objects you’re using, for code that runs on BeginPlay. You probably have a null reference error.

Check whatever you’ve changed since the last time it worked.

If you still need help, share a link to your GitHub, so we can look.

I would be curious to see of you launched the game from the command line if caught an error there? On windows is something like:

'C:\Program Files\Epic Games\UE_4.25\Engine\Binaries\Win64\UE4Editor.exe' 'C:\users\bryant\Documents\Unreal Projects\ThirdPerson\ThirdPerson.uproject' /Game/Sandbox -game -log

but use your UE4Editor path and your uproject path, and level. Note my level is in the content folder, but don’t include the content folder if you have a subfolder.

When run this it launches the game with no editor, but the -log will give some output

It would be helpful if you include more information. What lecture are you on? What did you do before you got this crash?
