Open my React + Vite project in StackBlitz.
Wait for the WebContainer to boot and dependencies to install.
StackBlitz automatically attempts to run the start command.
The preview fails and displays “Failed to run start command.”
The terminal shows ERR_NAPI_BINDING_TARGET_CONFLICT.
After the error occurs, I am also unable to type commands such as npm run dev in the terminal.
Refreshing/reopening the project does not resolve the problem.
Expected behavior
The Vite development server should start successfully and display my React application in the preview window. I should also be able to use the terminal normally.

Additional context
I am using StackBlitz in a web browser on a Windows computer. This is a React + Vite project. The WebContainer boots and dependencies appear to install successfully, but the project fails when running the start command. The terminal displays an ERR_NAPI_BINDING_TARGET_CONFLICT error. After the error occurs, I am unable to type commands in the terminal. I have attached screenshots showing the error and the “Failed to run start command” message.
