Flow separation on Ahmed Body 25º slant

Description: I have Flow separation on Ahmed body at 25º and I really dont know why.
Currently working on Altair Hypermes CFD 2024.1
I'm simulating the ahmed body in a Wind Tunnel.
I've done this simulations different times and none of them give me the proper results im looking for (flow not separating at slant).
I'm doing simulation based on this article for mesh parameters
I'm using 40 m/s for inlet speed, and I'm using walls for the top and side of my tunnel instead of Slip.
I have around 605k nodes. I know it could be a lot more but atleast I should have attached flow
I've done simulations before with the Ahmed Body and I've gotten the same results all the time, flow separation.
