So not just myself, but others I've been talking to have been consistently getting this error every time they close and re-open their Destiny 2 game on PC. For myself, the "Super" ability Key Mapping I reassigned never saves and goes back to a blank set bind that I have to reassign each time I play the game. Others are having issues with other assignment keys for other abilities. My question, are other people having this issue with assigning new key binds, is Bungie aware and has there been a solution to this yet (or upcoming)?
