I was able to get it working by manually updating trinity and quest tools to the latest version https://www.thebuddyforum.com/demonbuddy-forum/plugins/trinity/212606-trinity-2-8-4-questtools-3-4-16-a.html
I wasn't sure where this should be posted so here it is.
Greater RiftKeystones and Rift Trial Keystones are no longer classified as ItemType.KeystoneFragment, and are instead being defaulted to ItemType.Unknown.
This causes Zeta.Bot.Profile.Common.OpenRiftTag.OpenRiftTag() to only open...
From a little bit of investigation, it would appear that trial and greater rift keys are no longer classified as "KeystoneFragments" so the selection process is not working. This will require an update to demonbuddy to fix unfortunately :(
