delay on first run of LTeX CLI

[arantxax]

Describe the bug
I just downloaded ltex+ as ltex-ls to use as command-line/offline/stand-alone grammar checker. The first run should take long enough, but it seems that the server initialization is taking too long or has too many threads working on.

Steps to reproduce

1. Download ZIP file: ltex-ls-plus-18.2.0-windows-x64
2. Extract it in your desktop.
3. Create a "test" directory in your desktop.
4. Create a simple test.tex file in the "test" directory.
5. Copy the folder "ltex+" in the as subfolder in "test".
6. Go to "test\ltex+\ltex-ls-plus-18.2.0\bin"
7. Right click on the directory and select "open in Terminal"
8. ./ltex-cli-plus.bat ../../../test.tex --client-configuration=".lsp-cli.json" --verbose

Expected behavior
I want the server to be initialized and correct the grammatical errors in the tex document.

Sample document
This is the specific document in LaTeX:

\documentclass{article}
\usepackage[ngerman]{babel}
\begin{document}

\selectlanguage{ngerman}  % Explicitly set language to German

Ein Satz auf Deutsch Sprache.

\end{document}
