I seem to have a problem using SimXperience with Seat and Rear Traction Loss with F1 2021. The AccuForce steering wheel is working, but Motion platform is not working in the game. Only moves tiny bit at launch. I checked if firewall is opened for public and private network. The standard Telemetry setting on port 10001 doesn't work.
I managed to run a SimHub Dash on port 20777 though.
What may be the problem causing this is the error I get on the startup of F1 2021. "GamePluginInterface" error with content of "Out Error: Index was outside the bounds of the array." But I have no idea where it may come from.
