    Hi guys,
    I've been having a problem with SimTool 3 and iRacing for about a couple of weeks.

    The problem is this:
    When I start a race server, a practice server, or even a test drive, the SimTool application closes automatically, resulting in the dynamics system not working.
    If I restart SimTool, the application starts and the movement system works properly.

    In detail, what happens is this:
    - I start the PC
    - I start SimTool
    - I start SimPro by simagic
    - I start SimHub
    - I start iRacing
    - I select the server to drive
    - the iRacing server starts
    - the car is on the track and the movement system works.

    PROBLEM
    - I finish driving and exit the server
    - I choose another server and start it
    - Once the server is started, the SimTool application closes automatically and the movement system doesn't work
    - I'm forced to start the SimTool application and everything starts working correctly again.

    Every time I exit one server and enter another, I have this problem.

    I've also noticed this situation:
    - The iRacing server is active with the car on the track and the dynamics system working correctly.
    - I press the STOP button on the dynamics system in the SimTool app, the dynamics system stops.
    - I press the PLAY button on the dynamics system in the SimTool app, the dynamics system starts for a moment and then the application closes automatically.

    The dynamics system stops.

    Before a couple of weeks ago, everything was working correctly.
    I haven't had any Windows updates recently.

    Simtool 3 is up to date.

    The operating system is Windows 11 Home.

    My iRacing account is NOT through Steam.

    I still have Simtool 2 installed.

    Does anyone have a solution to this problem?

    Do you need more information?

    Thanks everyone.
