I can’t see my gun on the screen it disappeared

It happened during the match at least a multiple of times before. 
it even happened again in a different match than it pops back normally as back to the right way. It happened today. 

I call it ghost gun for about an hour in the first match. It definitely didn’t even respond as soon as I died plus it didn’t respond as come back alive. During each match’s in the game. As for 2 maps so far. 

it happened again yesterday last night when I was in a match for grinding up people in my area. It did last very long.
