Comment on attachment 184696 [details] Window is just white with title bar digiKam-8.8.0-20250903T170136-Qt5-Win64 Tried a prior version: digiKam-8.8.0-20250903T170136-Qt5-Win64
The problem is know and is relevant of the QtWebEngine component (Chromium based and embeded browser). Typically Chromium do not detect the GPU acceleration on your Windows and lock tha application. This have been already reported previously. Solution: in the digikam_systemrc INI config file: https://docs.digikam.org/en/getting_started/installation.html#configuration-files ... turn on an option about the GPU feature: Use the software OpenGL rendering: this option will disable the GPU hardware accelerations and switch to a software-emulation for all calls to OpenGL. https://docs.digikam.org/en/setup_application/miscs_settings.html#system-settings This is a view of my digikam_systemrc file contents: [System] disableOpenCL=true dnnOpenCLTested=false enableAIAutoTools=true enableAesthetic=true enableAutoTags=true enableDnnOpenCL=false enableFaceEngine=true enableHWTConv=true enableHWVideo=true enableLogging=false enableOpenCL=false proxyAuth=false proxyPort=8080 proxyType=0 proxyUrl= softwareOpenGL=true <==== THIS ONE!!! useHighDpiPixmaps=false useHighDpiScaling=false videoBackend=ffmpeg
It's not getting past the splash screen. First, I just set softwareOpenGL=true, but it didn't work. Still crashes. I also tried copying your settings, but it still crashes.
digiKam-8.8.0-20250917T050201-Qt6-Win64.exe is now running for me.
To clarify, although the 8.8.0-20250917T050201 preview now runs for me, it still crashes running "Rebuild all training data" Problem Event Name: APPCRASH Application Name: digikam.exe Application Version: 8.8.0.0 Application Timestamp: 68b67aaa Fault Module Name: nvopencl64.dll Fault Module Version: 32.0.15.8115 Fault Module Timestamp: 68a7690c Exception Code: c0000005 Exception Offset: 000000000003a68b OS Version: 10.0.26200.2.0.0.256.48 Locale ID: 1033 Additional Information 1: 7d07 Additional Information 2: 7d07c65ae3754639cc0d4531b9ea5f40 Additional Information 3: dd27 Additional Information 4: dd274a6eb8c7840129f706076afe775e
Fault Module Name: nvopencl64.dll It crash in the Nvidia OpenCL interface. OpenCL is not OpenGL and here OPenCL is used by OPenCV framework to speed up computation with the face management using GPU. Before to rebuild training data, go to digiKam setup dialog, Misc section, System tab, and disable "Use the OpenCL hardware acceleration" option. https://docs.digikam.org/en/setup_application/miscs_settings.html#system-settings Best Gilles Caulier
After disabling OpenCL, you must restart digiKam. Maik
Disabling OpenCL allows the app to stay running. However, it now just hangs at some random percentage. The UI is responsive, but the actual rebuild/training process hangs. I've tried it a few times and hangs at some point. This is with the latest: digiKam-8.8.0-20250918T170144-Qt6-Win64.exe
A DebugView log would be necessary here and could help. https://www.digikam.org/contribute/#windows-host Maik

I ended up nuking the database and started over. "Rebuild all training data" worked at least once after that. I will try to do it again at some point.
