Android USB Tethering - Random restarts

[Yoola]

I'm forced to use LTE for a few weeks until I'm back to regular cable, but phone (OnePlus 5T) is giving me headaches when playing PUBG whilst thetering connection from the phone. Ping is decent, down speed is pretty good considering it's LTE (~70Mbps) and upload is solid. Only problem is it's that phone randomly restarts the connection. It doesn't completely restart the phone, it just 'signs out' and reprompts me PIN.  I've tried booting phone in safe mode, that didn't help. Tried some methods from Google like replacing that USB network driver with Microsoft's driver, and that also didn't help. I'm kind of desperate at this point. 

EDIT: Trying PdaNet but latency is significantly worse and getting only 1/3 of the speed.
