How to fix Unity not moving after reloading scene?

If Unity freezes after reloading a scene, there could be several reasons and solutions for it.

1. There is an error in the script in the scene: Check if there are any errors in the script in the scene, you can view error messages in the console, and fix the corresponding errors.
2. Objects missing in the scene: After reloading the scene, certain objects may be missing, causing scripts to not run properly. Check if all objects in the scene are loaded correctly and if any are missing, manually add or re-link them.
3. The execution conditions of the script are not met: The script may contain certain conditions that need to be met for it to run. Check the conditions in the script, make sure they are met, otherwise adjust or remove the limiting conditions.
4. In Unity, the order of script execution can affect behaviors in the scene. You can adjust the script execution order by selecting “Edit” -> “Project Settings” -> “Script Execution Order” in the menu bar, ensuring that scripts run in the correct sequence.
5. Incompatibility with Unity versions: If the Unity version being used is not compatible with scripts or plugins, problems may arise after reloading the scene. Try updating Unity or communicate with the developers of the scripts and plugins to see if there are newer versions available.

If the above methods still cannot solve the problem, you can try recreating the scene or script and gradually add functions and code to locate and solve the issue.
