My viewport and renders look terrible

[Unixety]

Hi, Whenever I use the Web Geodata, it's fine, but the aftermath is that my viewport looks like I'm playing on a game with the lowest settings possible. It looks blurry, parts of meshes disappeared, and every time I try to zoom in, meshes and stuff disappear as well.

My viewport has the same problems, it suddenly showed UV textures, base colors. As well as relocating my entire world center, needing me to move my objects over 500 kilometers it seems. Worst part is my viewport looks like this :/

you need to increase the subdivisions on your subdiv modifier that gets added (or you can delete and add your own) and then ive had issues with massively-scaled areas not working so i edit the plane and shrink it down to like 25% of the original size, that seems to help.
