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.
