Tessellation near clipping plane error

So after messing around with these parameters, i come to find everything in my scene is broken. all the elements will not move in the viewport, colors are different, billboards are all oriented in the z vector. My sky BPs are not responding. Ive been experimenting with persistent levels, so I was manipulating the tessellated mesh in a level that i applied to my base… I have about 5-6 more level that im turning on and off frequently. They alll broke… Do you think that the tessellation could have broken everything? I have the displacement set to a high amount. 5000 units.

When i try to rotate the BP to get the billboard to rotate, it moves but stays in the same orientation… the translate widget does nothing, but the rotate widget functions.

Everything is pink… the same color as the material that i was using to displace. Textures are missing from other elements… it really seems like that it broke my entire project… super disappointing.

I would call myself a middle level user. but at this point im afraid to migrate the assets over to a new project because i have no idea what has caused this or whats going on under the hood. I live in BP land.
