So recently since the new season has dropped, I have been experiencing a new issue that seems to be linked with the new battleeye anti- cheat system. My game will either completely crash and close, or it will exit me out of my current activity with the error code: Plum. Now I have tried different methods and done just about everything with my firewall I can to allow it to work, which would work for most a day or two. The methods can be found at https://androidgram.com/destiny-2-plum-error-fixes-workarounds/ However, the permanent fix that I have found so far, actually has to do with running the administration mode on or off. Both of mine were off when I went into the settings for D2 which can be accessed by going to your steam app > Library > right click on destiny 2 for properties > Local files > browse > and lastly scroll down and you will see destiny2.exe and destiny2launcher.exe. Now once finding those, you can right click on both of them once more to access the properties, to which then you will find the administration settings in the compatibility tab. (If the compatibility tab does not show when accessing, just exit out of the properties window and access the properties again, it should show up.) Now lastly, what I did was turn the administration settings ON for destiny2launcher.exe and I turned it OFF for destiny2.exe. Sorry for the long explanation, wanted to make sure I was thorough but hopefully this can help some of you out there cause I know it was a huge pain for me. Let me know if you are confused on anything!
