NI Support sent me Version 6.7.0, but it doesn't help. Did anyone encounter such a problem and has an idea would could be the cause? Is it possible to let Kontakt create some kind of debug log file with a detailed crash report?
Backstory:
I completely reinstalled the current version of Windows 10 (erased everything), installed all the latest drivers for my hardware (using Snappy Driver Installer) and Native Access and the latest version of Kontakt 6. I switched Windows 10's Defender Firewall and Antivirus completely off, because otherwise Native Access wasn't able to start at all.
Kontakt 6 Standalone starts with the audio setup. After that, the GUI appears completely white and a few seconds later the program crashes. Changing settings in the audio setup do not help. Reinstalling Kontakt didn't help, deleting the registry didn't help. NI Uninstall RegTool did not help. Deleting the files in AppData did not help. Basically, I did everything that was described here https://support.native-instruments.com/hc/de/articles/115004169849-KONTAKT-crasht-st%C3%BCrzt-ab and nothing helped.
The Windows events show only a generic crash report in module ntdll.dll, nothing that would be helpful.
I can start the standalone-Kontakt.exe in Windows 8 compatibility mode, after that it also works without the compatibility mode. Maybe Kontakt is trying to write some settings and only manages it in Windows 8 compatibility mode? As I said, I have completely deactivated the Windows firewall and virus protection, so this should not prevent Kontakt from doing anything.
My programs (DAW Samplitude Pro X5, Plogue Bidule) also crash when scanning the 64-bit VST2 DLL from Kontakt. If I start the programs with Windows 8 compatibility mode, then the DLL is read and works. The VST3 version does not scan and crashes with and without compatibility mode.
My system specifications:
Windows 10 21H2 (Build 19044.1766)
Core i7-3770K CPU
32GB RAM
Motherboard ASRock Z77 Pro3
Audio interface Focusrite Scarlett 2i4 (2nd Gen) with firmware 1051, driver 4.102.4
Graphics card 1: NVIDIA GeForce GTX 670 (driver version 30.0.14.7360)
Graphics card 2: NVIDIA GeForce GTX 1660 Ti (driver version 30.0.14.7360)
Graphics card 3: Intel HD Graphics 4000 (driver version 10.18.10.5161)
I use six screens, all connected to both of my NVIDIA graphics cards, but I don't think that this is an issue.
