Re: Crashes on launch with or without a movie running

nvopencl64.dll is library of GPU drivers.

Looks like something corrupted in it. It can be in some cases after Windows 10 updates.
It can be fixed. Just reinstall NVIDIA GPU drivers with clean install option enabled.

Maybe it is Intel?
I see in the log:

12:37:43.653 [i]: CPU: Intel Core i7-8700K [base frequency 3696 MHz, 12 threads]

You have Core i7-7800K. It has intergated graphics. But I see in the log:

12:37:43.913 [i]: Video: 1 GPU OpenCL device(s) on Intel(R) OpenCL [OpenCL 2.1] (Intel(R) Corporation)
12:37:43.913 [i]: Video 1: Intel(R) UHD Graphics 630 (Intel(R) Corporation, ver.25.20.100.6374) [gpuID=21]: OK
12:37:43.913 [i]: Video: 0 GPU OpenCL device(s) on Intel(R) OpenCL [OpenCL 2.1] (Intel(R) Corporation)

It is wrong because OpenCL on Intel detected twice. Second time with 0 GPU OpenCL devices.
Try to reinstall Intel GPU drivers. Use DDU again.

Re: Crashes on launch with or without a movie running

Oh, i think it crashes because even if i choose 2080 as the rendering device, it uses both the integrated and the 2080. Cause i use both intel hd graphics and 2080 these days. Could you see if you could debug it in a future update to use either of the 2?

Re: Crashes on launch with or without a movie running

You can use GPU for:
1) decoding
2) SVP calculating
3) picture rendereing

You can check which GPU is used and change it.

Decoding. Just open LAV decoder options and choose Hadware Device to use: MPC-HC menu View - Oprions... - Internal filters - Video decoder
SVP. Use SVP context menu to select: Application settings - GPU acceleration
Rendering. Used GPU physically connected to your display. You can reconnect
