Issue launching extension ("spawn EINVAL")

Describe the bug
Whenever I open VSCode, I get a little panel popping up saying "Help panel unavailable", and then when I look at the extension runtime status, it has:

Uncaught Errors (1)

spawn EINVAL

To Reproduce
Steps to reproduce the behavior:

1. Open VSCode
2. Click on 'extensions'
3. Scroll down to 'R'
4. Click on 'FEATURES' tab
5. Click on 'Runtime Status'
6. See the error

Can you fix this issue by yourself? (We appreciate the help)

No

Environment (please complete the following information):

• OS: Windows 11
• VSCode Version: 1.92.1
• R Version: 4.4.0
• vscode-R version: 2.8.4

Additional context
I'm using Rig to allow for changing R versions

Start by reproducing the launch failure on Windows 11 with VS Code 1.92.1, R 4.4.0, and vscode-R 2.8.4, using the reported r.rpath.windows and r.rterm.windows settings. Trace which configured executable produces the spawn EINVAL error and verify that the extension runtime launches without the Help panel failure.
