Other scenes are working fine . If anyone knows a solution please help .

This is a known issue with the Editor. To resolve the issue, you will need to reload the project by either going to View → Reload or View → Force Reload.

Besides the manual reload, the only other option at this time is to use another editor like VS Code with the tool.
