Hey there @Robslap32! Welcome to the community! If this is only one project, It looks a bit like you have static meshes disabled. This can be corrected by turning on Lit mode as Clockwork suggested and going to Show
or Exbir
in your language and enabling static meshes.
However if this is for all projects, I agree with glitchered and this could be related to your GPU settings. If that is the case, may we know your specs?
