================================================================

not very useful stack trace, but its the message!

Steps to reproduce

• Download the MRP
• Open Project
• open node_3d scene
• selectr TrailRenderer node
• click on active (will run _process) in inspector
• then go to TrailRenderer's _process code and add a print("test")
• save script
• engine should crash
