Cannot pick up ammo / Zombie issues / Cannot kill barnacle

I’ve been having trouble with the game since the first time you could pick up trip mines. When I encountered the first trip mines to be picked up, the HUD said I picked some up but they did not appear in my inventory.

From this point on I have been able to collect very little ammo. I think there’s only been SOME shotgun ammo I’ve been able to pick up. I have encountered every other ammo (pistol, magnum, submachine, grenade launcher, grenades). At this point I have very little of each ammo, well below the max amount.

Also I have not been tracked/attacked by any headcrab zombies. They just die.

Also if I happen to get snagged by a Barnacle, no matter how much I shoot them they will not die. They eventually kill me, every time.

And finally, if I encounter a friendly NPC they will also die shortly after I see them.

The game was working fine up until this part. Nothing to my knowledge has changed.

What’s going on, and how can this be fixed on my end?

Let me know if there’s any further information I can provide.
