Thanks for the heads-up, but the problem may be with your system, rather than with PD.

I hadn't yet installed the update when I read your post, and I made sure that the MultiCam Designer worked normally. I then installed KB4535996 along with the .NET update (KB4537572) for Win10 1909 and rebooted.

I have no problems using the MCD after the updates, whether I use my nVidia RTX 2070 GPU or the built-in UHD Graphics 630 iGPU. I can load clips, sync them, record the angles and place the clip on the timeline.

If you'd like help in troubleshooting the issue on your system, please follow the steps in the Read Me Before Posting sticky thread so we can see your exact versions of windows, what kind of hardware is installed, and what drivers you're running.

In my experience, most of the system issues that show up with BSODs and PD are related to video drivers, but sometimes they're caused by damaged Windows system files or a corrupted user profile. The DxDiag report described in the sticky will help us narrow down what might be going on.

It may also help if you describe the exact steps you've made when the BSOD occurs. For example, there are several ways to open the MCD and import clips, and it's possible that one of the ways I didn't try does show the issue. Basically, the more details you can provide, the more likely we can help figure out where the trouble is coming from.

Hello Optodata,

Here are my computer specs in a nutshell

Intel Core i7-9700K 3.6 GHz Eight-Core LGA 1151 Processor
ASUS Prime Z390-A LGA 1151 ATX Motherboard
Ballistix 32GB Sport AT Series DDR4 3200 MHz DR UDIMM Memory Kit (2 x 16GB)
MSI GeForce GTX 1050 Ti 4GT OC Graphics Card
Samsung 500GB 970 EVO NVMe M.2 Internal SSD

Windows 10 Pro 64 bit
Adobe Photoshop
Nikon NX-D
PD 365

Everything worked (works) fine with PD as well as all the other programs I use, it's just the multicam function that makes PD crashing
Anyway, I have downloaded the latest NVIDIA Studio driver in the meanwhile, and let's wait and see. I have delayed KB4535996 in the meanwhile.

I can select the clips I want to use with MCD with right mouse click but as soon as I click the record button it goes wrong.
Anyway it works again for the moment, so let's see what the future will bring

OK. The "nutshell" specs don't really provide any useful info, other than to tell me that you and I have similar motherboards. In order to understand what might be going on at a deep enough level to figure out what might be causing BSODs, the DxDiag test results are essential.

Please post back with them if you'd like more help here. They're also required if you decide to contact Cyberlink tech support.

Hello Optodata,

Here are the results from the DXDIAG test, but after uninstalling KB4535996 everything works fine again.

Robert

Arenz,
You're getting warmer.
The actual Dxdiag is generated when you click on that SAVE ALL INFORMATION button. It creates a text file
of all sorts of important information, but not personal information.
That is the file members need to hopefully get a handle on your issue. HP Envy Phoenix/4thGen i7-4770(4@3.4GHz~turbo>3.9)

Thanks very much for attaching the detailed test results. They show that you're using a fairly recent nVidia driver, but I think it's the Game Ready version, rather than Studio Diver, which may be better suited for PD and creating videos.

That likely isn't the issue with your BSODs, just something to consider tweaking.

The most recent 10 serious crashes are all listed in the Windows Error Reports (WERx) at the end of the results, and the older ones point to PDHanumanSvr, which is a core component of PD and to CaptureNX-D, which is obviously from Nikon. The next 6 most recent crashes were generic BlueScreens that don't specify the source app/library by name, and the most recent crash was caused by the nVidia driver.

If I were you, I'd do the following steps in this order:

1. Uninstall PD and the Nikon software suite and reboot


2. Download and install the nVidia Studio Driver linked above, and choose just NVIDIA Graphics Driver. On the Installation Options page, chose Custom (Advanced) then select only the Graphics Driver and also check the Perform a clean installation box. This will force the installer to remove all existing drivers and then only install the new graphics driver. You may need/want to reboot


3. Reinstall PD and verify that you can edit in the MultiCam Designer without crashing


4. Reinstall KB4535996, reboot and try PD with the MCD again. If the crash still occurs, you should request tech support here.


5. Once PD runs normally even with the KB update istalled, you can run the nVidia installer again if you want to add any of the game-specific features that PD doesn't need, and then test again to make sure they aren't causing trouble with the MCD


6. Likewise, reinstall the Nikon software suite and confirm that PD is still stable

Hopefully going through tese steps will get you running smoothly again

Thanks a lot Optodata,

The latest NVIDIA driver I recently installed is the studio driver so that should be OK.

But I will follow your advice concerning reinstalling PD, Nikon NX-D and the NVIDIA driver. I am not a gamer but only use that computer for video and photo editing.

Will keep you posted

Sounds good. You can skip step 6, and just do the other steps as explicitly written.
