Unable to Launch VSCode from Command

I have tried the step "Workaround No.1" described on the reference page below, but I cannot launch VSCode from the Mac terminal.

Page for reference:
[Visual Studio Code] command fails to launch VS Code (Mac Edition)

Workarounds 1

"Also, if you use the ""Workaround No.2"" method on the same page, it will look like an image."
There is an explanation that it cannot be changed because it is read-only, so I cannot proceed.

In the first place, the reason why I use the command to start is because even if I look at the file modified in VScode, it doesn't show as modified in the terminal git status.
I would appreciate it if you could let me know if you have any hints.Thank you for your cooperation.
