this shouldn't be built if (!enable_extensions)
can the assert stay? only chrome/browser/ui should be depending on this.

You're right. Problem was that chrome/browser/ui/BUILD.gn had an unconditional
dep to //apps/ui/views (=this file). In PS5 I've fixed
chrome/browser/ui/BUILD.gn instead of patching this file.

   sources = [
     "app_window_frame_view.cc",
     "app_window_frame_view.h",
   ]
 
   deps = [
     "//cc/paint",
     "//chrome/app/theme:theme_resources",
-    "//extensions/browser/app_window",
-    "//extensions/common",
     "//skia",
     "//ui/gfx",
     "//ui/strings",
     "//ui/views",
   ]
+
+  if (enable_extensions) {
+    deps += [
+      "//extensions/browser/app_window",
+      "//extensions/common",
+    ]
+  }
 }
