Reproducible with: 2021.3.35f1, 2022.3.20f1, 2023.2.10f1, 2023.3.0b7

Reproducible on: Windows 11 Pro, Windows 10 (Reported by user), macOS 13.6.4 (Reported by user), Ubuntu 22.04 (Reported by user)
Not reproducible on: No other environments tested

NOTE: this bug happens because we are tyring to create a script named "new" (see video) and the class name will also be called "new" which is an error in C#.
