Default Ansys getting stuck after hybrid initialization

svantevid is on a distinguished road
I'm doing filtration simulations in Fluent and from time to time it gets stuck after finishing hybrid initialization. After 10 iterations and a notification that Hybrid initialization is done, Fluent freezes as if it has not finished calculation. I cannot pinpoint the cause of this, once I fixed this by remeshing sometimes even that does not work.

EDIT: I did find a pattern, this only (but not always) occurs when the model rotational period is 180.

Has someone encountered something similar? Does anyone know what does Fluent do in the background after it finishes 10 iterations in hybrid ini?
