I have over 20 GB of VRAM because of the 3090 and 64 GB of regular RAM.
I have found the pattern to this bug, it took a number of hours but here's what I found:
The trigger/pattern to this bug (I am still calling it a bug based on these results) is that I must remove all types of a species (gender specific) so that the bug does not trigger, when I go to add a new animal, whose species and gender is not in my zoo yet. It does not matter if I add 10 female American bison, if one exists already in the zoo already it will add the animals without the triggering of this bug. Here's an example: Removing 10 female flamingos does not help to stop the bug from triggering if one female is left, however if I remove all 11 female flamingos the bug will let me add another species (one of its gender). What this also means, is that I can add as many flamingos as I want as long as there was one of its male or female genders already existing without the bug triggering, but if I try to add one female penguin, when I don't have one at all in the Zoo, the bug will trigger because there are no female penguins in the zoo. It is gender specific, meaning that if I am able to get a male penguin in zoo without the bug triggering, I can add as many male penguins as I want, but I still cant add a new female penguin unless a female penguin exists in the zoo. I would have to remove all females (or male) of another species in the zoo to add the female penguins without the bug triggering (the number does not matter, it could be all 11 female bison, or all 2 female warthogs, as long as its all the gender of a species. This may be hard to follow, so I created a video demonstration to show this in action. See YouTube link below. Using the new knowledge of the pattern/trigger, I was able to control the bug being triggered. Please check out the video and follow the step by step walkthrough in its description.

For those having this bug, please check out the video demonstration and see if removing all of a species that is already in your Zoo, allows you to add new animals so its not blurry. You may have to add more than one species to get to where the textures are not blurry and you control the such as I do in the video. I have contacted Frontier Support and hopefully they will investigate it using the new Info I discovered and generate a solution so that those with this bug can start adding all animals freely without doing the workaround done in the video.
