TheInput:GetWorldPosition() can return nil?

PlayerActionPicker component's DoGetMouseActions will need to handle the case when position is nil. Input:GetWorldPosition() in input.lua can return nil if the screen projection fails.

I search in the game and theres more cases it doesnt handle when Input:GetWorldPosition() return nil, like placer and player controller. Can you handle them as well?

Please help me, I really want to fix this problem. More than 3,000 days of playing time me and my friends have invested a lot, and we don't want to lose it.
Our 3,000 day games crashed, I found the cause of the crash is scripts/prefabs/wagstaff_npc.lua of 928 lines of code "local x, y, z = inst. Transform: GetWorldPosition()" returns nil, I don't know what to do. Here is my full DebugTrace info;
By the way, the game version is v590113(64bit).
