I experienced this earlier today. Reloading the last checkpoint (Talk to Vik, I think) helped me to be able to proceed. There are a lot of bugs in "The Pickup" it seems. There is a part when trying to escape All Foods, I have no gun at all. I had a gun in the beginning when I killed Royce then when trying to escape, I couldn't equip a gun... even a gun that I picked up while killing the enemy stealth-ly. I started a new game because there was no way in hell I could proceed without a gun. On the second run of the new game, I now had one.
