Hi Phillip
I saw in your message that you are using Windows 10.
I suggest reading or sending a message to this topic.

It was unclear if this is a fresh install or if it happened to have this problem after something.
Maybe a track, carshape or something else that was put in the installation.
If that's the case, it would be interesting to test one thing at a time until you get to what's causing the problem.
I would say by elimination
For example this only happens with track "xxx" in slot "y" or this happens with all tracks.
Feel free for anything.
Here you can attach a file via Mediafire with the screenshot and the log.
I don't guarantee to solve it but it's good to help and learn.
