I tried cache clean --force and tried to uninstall and installed nodeJS and chocolatey dependencies and manually deleted npm cache folder in AppData\Roaming. Still getting "JSON Parsing error" when running the command.

Any other suggestions to resolve this issue would be really helpful. Please let me know for any additional information. Thanks!!
