5.2.1 Crashes on startup

Is there an existing issue for this?

• I checked and did not find my issue in the already reported ones

Describe the bug

Installed latest version 5.2.1. from darktable website on W11. Running it first time gives splash screen, last message 'Initializing LUA' and then nothing, sort of. Application remains active, icon still on taskbar, and when clicking it two small windows flash up and disappear. That is it. lock files are still there (and will be removed when DT is killed).

OpenCL seems ok, and also starting without openCL gives same behaviour.

Steps to reproduce

1. Download
2. Install
3. Run

Expected behavior

Darktable should start normally

Reproduce the first-run startup failure with darktable 5.2.1 from the GitHub release on Windows 11, noting the last splash-screen message and the two startup modes with and without OpenCL. Collect the missing startup logfile and use it to isolate why initialization stops; done means the application starts normally.
