Initial Theory

Relative Paths are being passed to the server config, but it expects full paths.
Prior to 1.9.1 full paths were used.

This change in index.ts works makes it work fine.

  const namespacePaths = (await Promise.all(packageDirs.map((dir) => glob(`${dir.fullPath}/**/lwc`, { absolute : true })))).flat();

@dmchaplin Thanks for the PR! However, according to glob documentation:

absolute Set to true to always receive absolute paths for matched files. Set to false to always receive relative paths for matched files.
By default, when this option is not set, absolute paths are returned for patterns that are absolute, and otherwise paths are returned that are relative to the cwd setting.

Since our pattern is absolute, it should always be absolute. And, on my machine (mac), I see that it's absolute. Is that not the case on your machine? Is it dir.fullPath that's not absolute or is it glob that's not returning absolute paths?

@abdulsattar Thanks for the response.

I did a quick check. dir.fullPath is returning the full directory so it appears to be the Glob. It's strange that Glob is not returning the Default behavior. I use a PC but I don't know if if I have global setting somewhere that is overwriting behavior.

I appreciate the work you did to get multiple directories supported! This tool has so much protentional and a huge step forward from the old Local Dev Server.
