Premiere Pro CC 2020 on XPS 15 2-in-1 (9575)

Question

Premiere Pro CC 2020 (along with Rush and AE) crashes when loading media.

The system is brand new out of the box and features two display adapters where Intel HD Graphics 630 (no VRAM) is the lead controller and a Radeon(TM) RX Vega M GL Graphics with 4GB HBM2 Graphics Memory wich as I understand is the supplier of GPU power for among other programs Premiere.

This however does not work as Premiere and the other programs that render video crash and the system locks up and needs to be restarted for another try.

I found that the only thing that lets me work in Premiere is to disable one of the adapters.

Results are:

Disabling Intel HD Graphics 630 reduces the light strength in the panel with about 50% wich obviously is not an option. And I cannot control the brightness.

Disabling Radeon(TM) RX Vega M GL robs me of 4GB VRAM and makes the Intel adapter steal fram my system RAM of 16GB which is neiter an option.

Any suggestions for making these coexist? Thanks in advance.

If Premiere Pro is unbstable in that system, here is the reason:

You have a major conflict between the integrated Intel graphics and the discrete Radeon GPU - both of which use OpenCL for GPGPU acceleration. And neither Adobe nor the OpenCL consortium had updated OpenCL support significantly in many years, so it is effectively stuck at year-2012 levels of compatibility even in its officially licensed standard version.

Therefore, the ONLY way that you can work with Premiere Pro is to completely disable MPE GPU acceleration entirely and semi-permanently lock the MPE renderer to the software-only mode when you open a new project. And that is not to mention the severe quality control issues with all GPU-accelerated output via recent Radeon discrete GPUs.
