So far, I haven’t experienced this problem on PlayStation 4. Whenever I’m running and press one of the inventory buttons, it opens the inventory no problemo. But I’ve noticed that sometimes (not all the time) while I am running and I try to open my inventory, it doesn’t open. It generally depends on RNG if it’ll open my inventory or not. Sometimes when I try to open my inventory while running, it makes the declinded ‘ding’ sound. Others, it simply just doesn’t do anything. I do have an older laptop and runs hitman kind of slow, but I don’t think this should stop the inventory from opening at all, neither the less make the declined action sound while attempt. I should also mention my inventory always opens when I’m in an area with not many NPCs in the room, rooms nearby and in floors nearby above and below.
