Утечка памяти в JavaModuleWrapper.mModuleHolder ⇐ Android

[Anonymous]

Я использую React Native v0.69 для интеграции с существующим собственным приложением. Я следовал руководству по интеграции и обнаружил утечку памяти. Я упростил свою базу кода, чтобы иметь возможность отслеживать ее и находить решение, но не вижу способа это исправить.
Я также уведомляю об этом сообщении об ошибке, исходящем от реакции Native, сразу после Я закрываю это действие

Я также могу отслеживать это в Profiler в Android Studio, это подробно:
