I've been having the exact same issue that you describe, but only since this season has started. Stutters during character selection, when my ship is flying in, when I open my inventory or examine any weapon or armor. Crashes with a black screen when my ship right after it "reaches" the destination (music keeps playing most of the time). Every 5-10 tries it actually loads me in and lets me play without any issues, but the session after that always crashes again. I barely played Destiny 2 in the last two weeks because of these crashes, which is a shame since this season has been pretty cool so far. All the other games I've been playing have been totally fine, so it's just Destiny that's having trouble. My PC hasn't changed at all since the beginning of the year. Reinstalling the game and my graphics drivers hasn't improved things either. I have a Ryzen 1700, a GTX1080Ti and 16GB of RAM.
