localhost:8080 loads forever

Expected Behavior

• pdoc3 at least loads up a the top-lv documentation on localhost

Actual Behavior

• localhost:8080 loads forever

Steps to Reproduce

1.run pdoc --template-dir .\docs\config\ --http : .\spotdl\ from the root of this repo

Additional info

• pdoc version: 0.9.2

• I essentially want the spotdl.defaults subpackage to be rendered, running pdoc -http : spotdl.defaults insteads loads up the installed version of spotdl (a modified personal copy of spotDL/spotify-downloader)

• It works just fine for every other package I've tried so far

When I use the --http : flag, nothing happens, localhost:8080 just loads forever (a very long time)

Reproduce the reported pdoc --template-dir ... --http : ... command from the issue and inspect pdoc/cli.py, especially _generate_lunr_search at the traceback location and the CLI entry point. Compare the HTTP path with the normal documentation-generation path; done means the local server responds at localhost:8080 and renders the requested spotdl.defaults documentation.
