    Description

      qmlls that comes with 6.7.1 and 6.7.2 crashes when used from the VS Code extension.

      I've did a debug build of the 6.7 branch, and here's the verbose output:

      Note that the problem doesn't happen with Qt 6.8.0.

      If there's something that we can do on the VS Code side to work around this issue, we'd be happy to implement it.
