android - Unity Android Build错误:无法读取PNG签名:文件不是以PNG签名开头

Question

我正在Unity中进行2D游戏。
为Android构建时，Gradle构建失败，并出现以下错误:

CommandInvokationFailure: Gradle build failed. 
C:\Program Files\Unity\Hub\Editor\2019.1.14f1\Editor\Data\PlaybackEngines\AndroidPlayer/Tools\OpenJDK\Windows\bin\java.exe -classpath "C:\Program Files\Unity\Hub\Editor\2019.1.14f1\Editor\Data\PlaybackEngines\AndroidPlayer\Tools\gradle\lib\gradle-launcher-5.1.1.jar" org.gradle.launcher.GradleMain "-Dorg.gradle.jvmargs=-Xmx4096m" "bundleRelease"

stderr[

FAILURE: Build failed with an exception.

已经检查我提供的Appstore .png图片是否损坏，不是。
因此，这在构建过程中会以某种方式发生。
有办法调试吗？
我是否缺少阅读错误日志的内容？

我感谢任何可以帮助我研究解决方案的提示。
非常感谢你!

找到损坏的文件所在的文件夹:
Assets \插件\ Android \ native_plugins_lib \ res \ drawable

修复损坏的文件修复了我的问题。
