When the Logitech G29 is connected and the Logitech G Hub is open, the game will drop frames and freeze constantly and cause the wheel to fling left and right veering the car off road.
I have tested this with both keyboard and DualSense PS5 controller (wired) and both don't cause this same issue, so it must be a Logitech Issue. I saw on the investigating bugs forum post that this issue is on Xbox, but it also appears to be on PC too. This has been happening since the Patch v1.06, as before this I had pumped 100+ hours into the game with the G29 wheel on this year's game alone, along with 1000s of hours on previous titles with the same wheel.
This is not an overall PC issue as far as I am aware because my PC does not freeze, only the game. Everything on my second monitor continues to run smoothly whilst the game is freezing and dropping frames.
Please see my PC specs below for reference (the game is installed on my D: Drive):

I have also attached a video of what this issue looks like in Grand Prix mode (at the 5 and 6 second mark is where the exact issue happens)
