Disappearing left arm. (Half-Life: Alyx)

Hi all.

On Oculus Rift's noticed a bug in the game personally, I have sometimes disappeared left hand. In it, you could still stick a syringe with health (which says that the tracking controller works properly), for example, but to interact with objects or get out of a backpack is impossible. After some time, the problem was treated by itself, but the next 2 minutes just had to run and hide from enemies until the hand again back into place.
At first I thought that cant happen when inadvertently hand caught on something or gets stuck, but it's not. The problem manifests itself randomly. It has been probably a little more than half of the game and was 3 times, so the bug is not too serious, but, nevertheless, he is. Did anyone have something similar? If Yes, how did you solved the problem?
