Invisible Objects in Blender viewport. But not in cycles rendered view?

I recently got this weird thing where all of my objects are invisible in the viewport:

Eevee solid view

Eevee Material Preview

Eevee Rendered Image

I dont know how to fix it. Only when i change the engine to cycles and render the image it look normal, but other than that i cant find a fix. I tried to google it, but nobody seems to have the same problem. Any help is appreciated!!

Cycles Rendered Image

Thanks in advance!
