Ark is designed as a multiplayer game:
a server, which handles all logic and assets, but without the graphics, all dinos are computed without holding the graphics infomations. the server sends only the dino relevant data to the clients, like positions and rotation and some states.

the clients handle the graphics and the user actions, like inputs and the user interface.
the client render the dinos graphics and the environment.

in the past the singleplayer and non-dedicated server game does both, handling all logic and calculating all things related to non-static things in the game and the host must also handle all graphics, sounds, user interactions and user interface.

because of this, the ark devs implemented for the single player game a hibernation mechanic.
This hibernation mechanic removes all dinos not in the players visual range from the game and stores them internally, there is no way to get any information from this internally saved data.

The CreatureFinderDeluxe (CFD) mod collects all dino data from the game, using the search options the player did.
In a multplayer game the dinos data are fetched from the server, which can also cause lags, if the player searches without any filter.
But this will mostly not being noticed by the player.

In a Single Player game the mod can only collect the dinos data, which are accessible from the game.
All hibernated dinos aren't in the game. Because of this CFD can only find the dinos in visual range.

We are talking of about nearly 25,000 wild creatures.

The ark devs implemented later the -preventhibernation start parameter, because of complains from some player.
If your computer does not have enough RAM and processor power, the game becomes instable.
In my expirience you need a modern i5 and minimum of 32 GB RAM and of course a SSD.

With the -preventhibernation start parameter the hibernation mechanic is disabled, and CFD can find all dinos on the whole map.

Because of this i do not recommend the -preventhibernation start parameter.
I prefer a local server/client setup described in this discussion:

To recover a crashing save game on a save with -preventhibernation and disabled CFD:
(1) re-adding "-preventhibernation" and this mod and loading my save.
(2)Then, using DestroyWildDinos command to wipe map of dinos and exiting to main menu.*<--This saves the game.*
(3) Now i remove "-preventhibernation" and test loading my save with mod but no "-preventhibernation" this time and it worked. I think wiping dinos from save is the key to safely removing the mod.
