Hey, so I opened the scene and it was complaining about zGeo9:
// Error: ziva ( 4.42s) ERR| zGeo9 - input matrix is not connected //
// Error: ziva ( 4.43s) ERR| Could not compute GeoNode `zGeo9'. //
I looked in the node graph and saw that there was no mesh connected to this node, so I just deleted it.
The scene now solves fine -- can you check if this works at your end? 🙂
