根因分析

AssetBundle文件已损坏或使用不同版本的Unity构建，导致加载时CRC检查失败。

English

AssetBundle file is corrupted or was built with a different version of Unity, causing the CRC check to fail during loading.

解决方案

  1. 使用将加载它的相同Unity版本从原始资源重建AssetBundle：BuildPipeline.BuildAssetBundles(outputPath, BuildAssetBundleOptions.None, BuildTarget.StandaloneWindows64);
  2. 如果捆绑包来自远程服务器，请重新下载以确保完整性：使用UnityWebRequestAssetBundle.GetAssetBundle(url);

无效尝试

常见但无效的做法:

  1. 95% 失败

    Manually editing the AssetBundle file to fix the CRC is impractical because the CRC is computed over the entire file and cannot be easily recalculated.

  2. 60% 失败

    Disabling CRC checks entirely via AssetBundle.LoadFromFile with crc: 0 ignores corruption and may cause undefined behavior later.
