IDEA升级或重装后不能启动问题

之前用代理安装过2019.3的IDEA，最近新买了licence 重新安装2020.3版的后一直没有起来。

报道如下错误：

D:\software\JetBrains\IntelliJ IDEA 2020.3.2\bin\
OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.
Error opening zip file or JAR manifest missing : D:\software\JetBrains\IntelliJ IDEA 2019.3.5\bin\jetbrains-agent.jar
Error occurred during initialization of VM
agent library failed to init: instrument
请按任意键继续. . .

　通过调试D:\software\JetBrains\IntelliJ IDEA 2020.3.2\bin\idea.bat发现，在以下目录中有引用，删除对应的jetbrains-agent.jar配置即可
