Unable to confirm if there is an issue with exporting using template_debug, as neither the GitHub Actions in the Godot repository nor my computer have a build for template_debug.

Steps to reproduce

In the project settings, change the Linux display service to wayland (or run the project with --display-driver wayland), and the log shows ERROR: Can't connect to a Wayland display.

Oh... I might have put the socket connection logic inside the TOOLS_ENABLED #ifdef xD

Thank you for catching that!
