问题背景 #

长期使用PyCharm Community Edition 2023.3.7，突然无法启动，点击后无任何反应。尝试重装、更新均无效，通过CMD运行程序时触发JVM致命错误，日志如下：

问题分析 #

日志显示JVM在调用ASProxy64.dll时触发EXCEPTION_ACCESS_VIOLATION（内存访问违规），该文件通常与系统代理、安全软件或网络组件相关，并非PyCharm本身代码问题。

解决步骤 #

• 关闭全局代理：打开系统设置→网络和Internet→代理，关闭“自动检测设置”和“使用代理服务器”，再尝试启动PyCharm
• 临时禁用安全软件：暂停杀毒软件、防火墙等防护工具，排查是否是它们拦截了ASProxy64.dll的加载
• 替换自带JBR：
  1. 下载对应版本的JetBrains Runtime（JBR-17.0.12+1-jcef）
  2. 找到PyCharm安装目录下的jbr文件夹，备份后删除原文件夹
  3. 将下载的JBR解压到该目录
• 清理配置缓存：
  1. 打开C:\Users\<你的用户名>\.PyCharmCE2023.3目录
  2. 删除cache和system两个文件夹
• 修复系统文件：以管理员身份运行CMD，执行sfc /scannow修复可能损坏的系统dll文件
