Hi Alicia
I have the exact issue on a Windows Machine. Also running latest version of neo4J Desktop and GDS with a 4.2.6 database.
Security configs are like this on both machines:
Those configs should allow GDS to function.
Any advice on next steps would be appreciated. There is no immediate urgency. I will kill one of the machines and re-install, etc. Any success I will post here.
Regards
Jonathan
