Windows 11

What issue are you seeing?

Codex Desktop on Windows cannot use the Chrome plugin because node_repl fails to start its JavaScript kernel. The Chrome browser, Codex Chrome Extension, and native host configuration all appear to be installed and healthy. The failure occurs when node_repl attempts to start its Windows sandboxed kernel.
