    Same crash on 2021.3.11f1 Android using assetbundle built from 2019.2.21.
    What should we do?
    Upgrade Unity to 2022.1?
    Or rebuild all assetbundles on 2021.3.11f1?

    For anyone still suffering from this and not wanting to jump to a non-LTS version of Unity:
    I had this exact error when upgrading from 2020.3.23f1 to 2021.3.9f1, where previously it behaved fine. Thankfully the simple fix was rebuilding the win64 bundles. Seems like the bundles built in a previous version of Unity were no longer compatible. I also deleted the meta files in Finder/Explorer and let it regenerate those, but I'm not sure if that part was needed.
