How to Fix "Unity Editor Crashes on Startup"

If Unity crashes on startup, it can be due to several causes, such as corrupted files, conflicting plugins, or hardware compatibility issues.

Here’s how to fix this problem: First, check the Unity Editor log for any error messages that could provide clues about the cause of the crash.

You can find the log files at the following location: C:\Users\Username\AppData\Local\Unity\Editor\Editor.log on Windows, or ~/Library/Logs/Unity/Editor.log on macOS.

Open the log file to see if there are any specific errors or issues that need to be addressed.

If the log file shows that a specific asset, script, or plugin is causing the crash, try disabling or removing it.

One of the most common causes of crashes on startup is corrupted project files or Unity installation files.

Try creating a new Unity project to see if the issue persists.

If the new project works, the problem is likely with the project you're trying to open.

In this case, try deleting the Library folder in the project directory and then reopening the project.

This will force Unity to re-import all assets and rebuild the project files.

If the issue persists, try reinstalling Unity.

Sometimes, a corrupt Unity installation can cause crashes, so uninstalling and reinstalling Unity can resolve the problem.

If you are using third-party plugins or assets, they may be causing the crash.

Disable or uninstall any recently added plugins and see if the issue is resolved.

Make sure that all plugins are compatible with your version of Unity.

Another step is to check for any system updates.

Outdated drivers or operating system versions can cause crashes.

Ensure that your graphics drivers, DirectX (Windows), or Metal (macOS) are up to date.

If Unity continues to crash, try running the editor with administrator privileges to ensure it has the necessary permissions to access system resources.

Finally, check your hardware for issues.

Unity requires a certain level of performance to run smoothly, so ensure that your system meets the minimum requirements for running Unity.

If you're using integrated graphics, try switching to a dedicated GPU for better performance.

By following these troubleshooting steps, you should be able to fix Unity crashes on startup.
