Fusion crashes upon opening

Hello,

I am using DaVinci Resolve 15 - Public Beta
macOS High Sierra,
working with Pro Res 422 and Go Pro - H.264 files
and every time I try to open Fusion it crashes.

Is there an easy fix to this?

Thanks

Stand alone Fusion or the Fusion tab of Resolve?

If it is the Fusion tab of Resolve it would be better to ask in the Resolve section of the forum. Also you should upgrade to Resolve 15, the beta is over and it was released.

Do you by any chance have an older version of Fusion installed from before?
