在Intellij IDEA 2019中，我错误地将错误的行添加到VM选项文件（菜单|说明|编辑自定义VM选项）。之后，IDEA不启动。重新安装也没有帮助。当我从终端运行IDEA时，它给出以下错误：

~/.local/share/JetBrains/Toolbox/apps/IDEA-C/ch-0/193.7288.26/bin$ ./idea.sh

OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated 
in version 9.0 and will likely be removed in a future release.
Error: Could not find or load main class org.gradle.jvmargs=-Xmx2048M,
-XX:MaxMetaspaceSize=512m Caused by: java.lang.ClassNotFoundException: 
org.gradle.jvmargs=-Xmx2048M, -XX:MaxMetaspaceSize=512m

但同时，这些行不在idea64.vmoptions文件中：

~/.local/share/JetBrains/Toolbox/apps/IDEA-C/ch-0/193.7288.26/bin$ cat idea64.vmoptions

-Xms128m

我不明白是什么错误。有人能帮助吗？感谢您的评论/回答！
