Hi,
I had a similar issue last week with tyCache crash and current Tyflow and provided already my file.
Maybe it has to do also with the „explicit normals“? (something Tyson mentioned)
My scene used also edge fracture, but I did not examine if that could have to do with Edge Fracture)
In my case I used tycaches with Birth Flow, and theses caches had been created with use of edge fracture.
