    Maybe it is would be better not using of BinaryFormatter at all due to "Deserialization risks in use of BinaryFormatter and related types" described in particular post at learn.microsoft.com

    Hello we run into this issue with running Android on the Oculus with Unity 2021.3.16 with byte arrays.

    Reproducible in Android Unity 2021.3.16

    not sure but it might help,

    we have our project in unity 2020.38.f1, tried to update it to newer versions and stuck with the same issue, then to make things simpler created a new project to quickly check on different unity versions, findings below..

    BinaryFormatter.serialize() produces the InvalidCastException only for Integers jagged arrays, rest of the basic type variables jagged arrays are fine(float, string, bool), this happens only on the build and not in the editor.

    tested only on Mac OSX for editor and on iOS build,
    in editor, its all good, no errors at all in any unity versions, BinaryFormatter.serialize() will work perfectly fine as it should do for integers jagged arrays, but will through error in the build.

    if you are loading saved data previously saved through BinaryFormatter, no issues at all, it will load the integers jagged array without any problem.

    produceable on unity 2020.3.44f, 2021.3.16f1, 2022.* .

    not produceable on 2020.38f1, 2020.43.f1
