Marine X, you helped me get to the solution!!!
All I was seeing was the game freeze and stop working, or crashing but not being able to see anything in the crash logs I could understand to lead me to a conclusion. But when you suggested the netgraph, it made me think about connection stability. So, I started Googling/YouTubing ways to improve internet stability, followed a guide to edit my Ethernet adapter settings in Windows, and was just able to be in game for 25 minutes straight, flying around, using powers, and even changing zones with no freeze, crash, or other noticeable issues. I'll post here again if I have any more consistent issues after this, for the time being this seems to have done the trick! Thanks again to both you and Healix for reaching out to help!
