I don't think it has anything to do with the iGO software, but with the phone. Whether it is its hardware, driver or system.
At one time I had about 15 phones at my disposal (but never OnePlus), I tried and tested all editions, I have never had such a situation.
Actually, considering that Avic is written for dedicated devices, it is also possible that there is something in its code that has a conflict with OnePlus devices.
