My water is pink and I have no idea why… Ive tried searching for a solution but non of them fixed my problem… And also ive already tried reinstalling unity and made sure to delete everything. Pretty annoying because I cant even add a simple pond or river to my terrain… it looks pretty plain without it and I was making it with rivers and ponds in mind. Could really use some help here!

2This sounds as if their Base Material / Texture is missing.
you might want to try and see if the textures are with the water.
if the Material is there, check the texture on the Material < normally this is where the Pink Void comes from. ( when textures are deleted or removed from the Game engine.
The "fallback texture" isnt there... where would i get that texture from? I cant find a good water texture online and i cant re import the asset because it still wouldnt be there... update: ok, i went to cg textures and found a good water texture, but now that I've applied it to the material in the empty spot, the material is still pink...
– KevroaIt looks like you might be running into the issue I describe here: Reddit - Dive into anything which has broken your FX/Water (Basic) shader.
Try out the fix suggested there?
Instantiate(prefeb[prefeb_num], teleport[0].position, teleport[0].rotation );
