I'm afraid I also have this problem. I'm happy to provide any help or input, development / trace builds of the game or whatever. Running as admin, restarting computer, and disabling AV didn't resolve the problem for me. No noticeable events in the event viewer.
Specs, just in case it's important:
AMD Ryzen 5 2600 X 6-Core Processor 3.6 GHz
16 GB DDR4 RAM
NVIDIA GeForce RTX 2080
Windows 10 Pro 64-bit ver. 1909 OS build 18363.900
DirectX 12
