Ice chunk rolled and killed me and now all collectables are missing out of inventory

Hey so I was playing the game at a certain point a massive ice chunk rolls down and well it killed me. Then the game didn’t let me restart when it said reload last check point. It just was stuck on the death screen. Quit to lobby now stuck on “PLEASE WAIT Loading…”

Update The games loads buuuut all of the collectables in Act 2 I found are gone and I can no longer pick them up to refind them.
