Gear shift jumps after a while

I have the problem that my gear shift randomly switches to different gears after about 30-40 seconds of driving without me doing anything. I have all driving assistance systems turned off and drive a Logitech G29 with a G920 shifter. It´s very annoying and I hope someone has a solution for me.
I look forward to answers!

 

Not Beams fault, its shitty Logitech wheels

Yes, a lot of Logi's products are great, but their wheels, for lack of a better term, are absolute shit. Especially their shifters, they make their wheels with cheaper parts every year with outdated tech. Wanna know why the G27 lasted the test of time? because it was in an era of Logitech where they cared about their wheels instead of using them as a cash grab. Sorry for the rant.

Logitech wheels suck, not Beamng's fault

 

Ive had a g920 for something like 2 years now and im really hoping it stays good cuz i cant spend the money for a new nicer wheel lol

 

What I've found is that thier quality is very inconsistant

I've heard of peoples G29 lasting years with no issues and people like me where they end up doing weird shit after a year or so
Idk, still not Beams fault
