The game on Unity works but when I export it to Android it stops working. When I do build and run in the terminal it gives me the following error:

Its all about code stripping. If you want fast resolution, you can create link.xml file in Assets folder with next content:

<linker>
    <assembly fullname="Unity.ResourceManager" preserve="all" />
    <assembly fullname="Unity.Addressables" preserve="all" />
</linker>

If you don't use Addressables, next code:

<linker>
    <assembly fullname="Unity.ResourceManager" preserve="all" />
</linker>

Also you can do more strict code stripping rules. More information about code stripping you can find by this link.

If you are finding that the Localization package is not working in the build please try the following:

  1. Update to the latest Unity patch version
  2. Update to the latest Addressable Assets package in the package manager.
  3. Try disabling code stripping
  4. Clean and Rebuild Addressables. When Building make sure the Editor is set to the target platform in the Build Settings window.
  5. Try running the Localization Analyzers (0.11.0-preview). This can be found in the Addressables window. Link
