I am Korean, so the sentences may be strange.

As in the title above, an error occurs in the script. The file name and the script name are the same, and Visual Studio works well with an error message or a color display.enter image description here

I reinstalled Visual Studio, but it didn’t work. The solution was to change it from Debug mode to Release mode. However, when I try to edit the scene and save it, Unity crashes, and when I re-enter, it initializes and the error occurs again.

How can I solve this? If you don’t understand, please ask questions. Also, what is Release mode and how can it be solved? I am also curious about why it crashes.
