解決にあたって実行したこと

Docker Desktopを起動する
Settingsを開く
Docker Engineを開く
Daemon configuration fileを下記のように書き換える
[Apply&Restart]をクリックする

{
  "builder": {
    "gc": {
      "defaultKeepStorage": "20GB",
      "enabled": true
    }
  },
  "experimental": false,
  "features": {
-    "buildkit": true
+    "buildkit": false
  }
}
