解决方法
Caused by: java.io.UncheckedIOException: Could not read workspace metadata from C:\Users\itmob.cn\.gradle\caches\8.8\transforms\5e58dde8d255b1276439bb7095fc102c\metadata.bin
上述异常信息中提到无法读取 Gradle 8.8 的缓存目录中的元数据，缓存文件出现问题。
解决办法：根据异常信息将缓存目录下报错的 Gradle 版本的缓存文件全部删除，然后重新同步项目即可。比如：上文异常的缓存在 C:\Users\itmob.cn\.gradle\caches 目录下，有问题的版本是 8.8，删除 8.8 这个目录即可。
- 由于 Android Studio 正在占用某些文件，删除缓存可能失败，可以先关闭 Android Studio 再删除。
- 删除的目录中包含下载的 Gradle 依赖项，在下一次构建中将重新下载，这可能需要一些时间。
