Unexpected token in JSON at position 938

[G-R-A-F-F]

Hi,
All extensions are up to date
VSCode 1.44.2 (Linux Snap Package)

Steps to reproduce:
In python file highlighted some code:

def cls():
    if os.name == 'nt':
        os.system('cls')
    else:
        os.system('clear')

Ctrl+Shift+P -> Add-To-Snippet
Got the error.

I have an existing snippet file with some snippets.

Thanks for you feedback, I belive that error cause by some nonstandard JSON(such as {"key":"value",}).
To avoid this, i switch the JSON parser to microsoft's jsonc-parser, which used by vscode ,it should solve the problem.
