Thanks for the screenshot; I cannot notice anything irregular. They all look okay.
When you say it works great with other games - are they also on PC running via G HUB? Or Xbox?
I'm not sure if its relevant; but maybe
this post would help/has some relevance? Maybe the wheel is still in Xbox mode?
If you join the track (car in pit/track) and press "shift + c" to reinitialize controllers, does it make any difference?
Try a different USB port to plug in the wheel and check if that makes any difference.
Have you made any hardware changed other than what's been listed on the first post (changed any power adapters cable to the PC)?
Rolling back on the G HUB updates might be possible, to troubleshoot. But then again I'm sure a few of LFS racers use the same wheel and would have encountered the same issue if the G HUB update has messed up something...
Its better to check with Logitech support/forums (if any) before doing anything drastic...
