Random Blurriness on textures and lightmaps

So randomly all my textures and lightmaps have turned blurry. All settings are on epic and lightmaps have been scaled respectively. This just happened randomly out of no where. Any ideas why and how to fix this?

Is it only in editor viewports, or in game also?

Hello Kibbles26

What is your lighting quality for build? Preview------Production. Can you check it and build it with production please?
