Unable to load class 'org.jetbrains.kotlin.kapt3.base.Kapt'. Possible causes for this unexpected err
Unable to load class 'org.jetbrains.kotlin.kapt3.base.Kapt'.
Possible causes for this unexpected error include:
Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
Re-download dependencies and sync project (requires network)
The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.
Stop Gradle build processes (requires restart)
Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.
In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.
Try:
Run with --info or --debug option to get more log output. Run with --scan to get full insights.

实际造成这个问题是原本升级到 Kotlin 1.3.70版本（目前最新3月5号发布的），AS升级到了3.6.1，项目中有用到协程，所以都用更新到了最新，后面问题马上就如上图所示，gradle起不来了，查阅一通，发现大家都没有遇到过，后面追踪到实际错误日志，把
ext.kotlin_version = '1.3.70' 降到ext.kotlin_version = '1.3.60' 编译后一下子活过来了。
