Career Mode Trailer Issues

I've been playing career mode for a while now and have recently been using the T-Series a lot. My problem began when I realized that I could get a 20ft transport trailer and put 8 XL boxes in the container box while simultaneously hauling a trailer with the slide out 5th wheel.

Whenever I connected my truck to the trailer it would freeze the game and state that there was in instability with either the truck or trailer.

At first this was limited to the 20ft transport that I bought, I had hauled other trailers before (delivery and personal), and now I cannot haul anything at all without this happening. There are times where the game doesn't preemptively pause, then my truck violently explodes. Other times the engine just breaks.

I play career mode with no mods activated and even uninstalling all my mods did not work. I have not attempted a reinstall yet.

I have tried clearing cache and verifying game files and the problem still persists. I cannot replicate this in safe mode as my career profile does not carry over. This problem does not occur in freemode with or without AI traffic.

I understand that career mode is a work in progress, but this is really messing up my BeamNG experience and I would like to fix it if possible.
