試したこと

The following ArgumentError was thrown resolving an image
codec:
Invalid argument(s): No host specified in URI file:///で検索。以下のページにヒット。
info.plistに <key>FLTEnableImpeller</key>
<false />と記載すると解決したと記載していたので、記載するも再度同様のエラー。
画面遷移実装時に書いたコードもコメントアウトして再実行するも。再び同様のエラー発生。
以下、複数のページを漁るも、解決できなかったので有識者の方々にお力をお貸しいただきたいです。
