You should mention your specs, quality level settings (or more rendering settings if you changed any in Settings in Studio), and you could include the repro file showcasing the issue via a PM with a staff member.
If I disable your script called “Ambience”, the issue is resolved. That script is manipulating the Lighting service at run time, which is why it looks weird only when the place is being run. Please try disabling your scripts in the future before reporting a bug!
