What issue are you seeing?

Codex Desktop on Windows, app version OpenAI.Codex_26.429.3425.0, CLI 0.128.0-alpha.1.

Browser Use fails before opening a tab because node_repl cannot start Node:
failed to execute Node: Přístup byl odepřen. (os error 5)

Manual checks:

• node.exe runs from PowerShell.
• node_repl.exe --disable-sandbox starts manually.
• A wrapper CMD calling node_repl.exe --disable-sandbox works manually over MCP stdio and returns JS result 1+1 = 2.
• The same wrapper configured as [mcp_servers.node_repl_direct] in config.toml loads in Codex, but tool call still fails with os error 5.

This suggests the failure is specific to MCP server / Node kernel launch context inside Codex Desktop.

Additional UI issue:
The Artifacts / Sources popover opens on the right side and overlaps the vertical scrollbar. It prevents grabbing the scrollbar with the mouse. Esc, clicking outside, and the top-right panel button do not dismiss it reliably. This happens in Codex Desktop on Windows.

What steps can reproduce the bug?
