Setting aside the handful of warnings, you only have one recurrent error :
... when Base surface uses "Surface" as Outside Boundary Condition Object, subsurfaces must also specify specific surfaces in the adjacent zone.A "base surface" is an opaque wall or a roof, and in your case hosting one or more "subsurfaces" (e.g. doors, window, skylights). EnergyPlus is reporting that all of these interzone base surfaces are holding subsurfaces that do not have explicitly-stated outside boundary conditions. The fix is easy, as detailed in the IO Reference:
If Outside Boundary Condition for the base surface is Surface, this field should specify the subsurface in the opposing zone that is the counterpart to this subsurface. The constructions of the subsurface and opposing subsurface must match, except that, for multi-layer constructions, the layer order of the opposing subsurface’s construction must be the reverse of that of the subsurface.

BTW, a quick UMH search for "invalid blank Outside Boundary Condition" yields a dozen hits (some recent, some dating back 8 years or so) all offering the exact same advice. A friendly hint for future queries ...
