What's Wrong?

Hi there,

I've installed the plugin and properly configured the PATH environment variable to include the Claude Code executable. When I open the plugin via its icon, the terminal in the bottom-left corner works as expected. However, the bottom-right panel consistently shows the following error:

Cannot launch Claude Code

I’ve double-checked the following:

The plugin is installed correctly.
The claudecode executable is accessible from the Command Prompt (e.g., running claudecode --version works) and is included in my system’s PATH.
File permissions appear normal, and there are no obvious typos in the path.
Despite this, the right-hand side interface fails to initialize with the above error. Could you please help identify what might be causing this issue or suggest additional debugging steps?

Environment:

OS: Windows 11
Plugin version: 0.1.14-beta
Claude Code version: 2.0.76
Thanks in advance for your support!

What Should Happen?

After clicking the plugin icon and with claudecode correctly installed and in PATH, the bottom-right panel should launch Claude Code successfully without showing "Cannot launch Claude Code".
