Found no LWC components in the current workspace. (Relative / Full Path)

Start in index.ts at the namespacePaths glob construction and compare the paths passed to the LWC server with the package directories. Reproduce with the listed sf lightning dev command on Windows Git Bash, then verify the workspace reports the expected 55 LWC components instead of none.

Summary

Local dev is not finding LWC directories. While starting the plugin, I get the follow error:

[Module Graph] Found no LWC components in the current workspace, check your settings in lwc.config.json.
[LWC Dev Server] LWC Dev Server started at port:8081

Steps To Reproduce:

1. Using Git Bash
2. SF_LOG_LEVEL=trace SF lightning dev app -t desktop -n "My Cool App"

Expected Result

[Module Graph] Found 55 LWC components in the current workspace.

Actual Result

[Module Graph] Found no LWC components in the current workspace, check your settings in lwc.config.json.

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();
