Thank you for the response!

I had noticed that in NVIDA GeForce Experience settings (under the "Games" tab), the "Automatically optimize newly added games" setting was enabled. The issue mentioned in the prior post has not yet occurred since disabling this feature. I will continue to monitor it.

Notable also is that I have recently purchased and installed the Shadowbringers expansion. The black screen issue was observed only with the base game.

Thank you again for your feedback.
