Yesterday, I built a new Sigil with Qt6.9.2, including building the installer, but Sigil won't start. Today, I made further attempts, but still without success. Each time, Sigil builds without errors, but it just won't start.
* Windows 10 Pro 22H2
* Visual Studio 2022 17.14.15 (September 2025)
* VCTools 14.44.35207
* VCRedist 14.44.35112
From log (events):
This line is probably key:
Path of the module causing the error: C:\Program Files\Sigil\Qt6WebEngineCore.dll
What else can I do/check/debug?
