DaVinci crashes working in Fusion

Hi, DaVinci Resolve crashes when working in Fusion, trying add transition effect, or when I get the effects in it crashes when I try connect nodes. Have manage one time applying the effect and played I in Fusion tab with no problem but then crashed when I clicked on edit tab. Any suggestions how to troubleshoot?
