筆者の開発環境
- Windows 10
- Unity2020.3.23
- Nreal Devkit（2022年4月購入。メガネはNreal Lightコンシューマー版と同じ）
- Computing Unit（Android端末）は Android 8.1.0
- NRSDK v1.8.0
- 2022/8/9 追記：NRSDK 1.9.3 では Development Build で実機起動できるようになった
症状
- NRSDK Demo の HelloMR がビルド対象
- Unity の Build Settings の「Development Build」をONにして apk を作成
- Nreal実機にて apk を実行すると、以下エラーで起動できない

備考
- ちなみに、IL2CPPビルドはできた
- IL2CPP + DevelopmentBuild ON でも上記と同様のエラーだった
- Unityプロファイラなどは使えないが、DevelopmentBuild OFF で進める
- 実機で Unity Assert が無効になってしまうのが残念
