Appreciate the feedback, lemming! I don't find anything unusual with either of the logs (not that I have much experience looking at them), and no specific mention of any error. The launcher log has validation and installations of components, receives token, and seems to launch the game process successfully, reporting the PID that task manager confirms. The client log confirms the same command line parameters as the launch log, states the game engine information, mounts asset containers, preloads DLLs, reports data version, and the last line shows message stores were finished loading. That's all that's in the log files.
However, I also had the thought to enable the debug console, which provides a few more lines. Since it had hung here earlier with an earlier NVIDIA driver version, I updated that driver, but it has not changed the result of the game hanging after the last few lines of the debug display below.
