Severe AI teleporting / desync in Co-Op and Multiplayer Grand Prix PC

Hello,
I’d like to report a serious issue with F1 25 related to AI behavior in online modes.

My brother and I are playing on PC from the same house and the same internet connection.
The issue happens both with crossplay enabled and crossplay disabled.

In Co-Op Career mode and Multiplayer Grand Prix, the AI cars constantly teleport forward and backward, showing heavy desynchronization. Their movement is unnatural, with sudden jumps and position changes, making races almost unplayable.

Important details:
Both players are on PC
Same local network same Wi-Fi, same house
Stable internet connection, works perfectly in all other online games
Issue occurs only in F1 25
Occurs consistently in Co-Op and Multiplayer Grand Prix
Crossplay ON or OFF makes no difference

This does not appear to be a local connection issue, but rather a server-side synchronization or netcode problem involving AI cars.

Thank you.
