[Bug]: Crash/freeze with blank window

Installation Method

Local Installation

The Problem

Several seconds after launching stirling by clicking on shortcut on desktop window becomes blank (screenshot). Logs attached when stirling's windows is on screen. Stirling is installed as desktop app by using msi installation method. I tested server version in browser and it works but I prefer using this as app. And I attached screen of site which is provided in log at the end.

Version of Stirling-PDF

2.14.3
