最近遇到个问题，每次用 Android studio 切换工程后，直接将 mac 的系统搞重启，再次打开 Android studio 依旧可以把系统搞重启，死循环。 尝试过的方法

1. 升级 macOS 系统，从 Mojava 升级到 Catalina 无效（两个版本都有这个问题）
2. Androidstudio 3.5 和 3.6 版本均无效
3. invalide cache 无效 4.在 studio.vmoptions 配置 -Dsun.font.layoutengine=icu 无效

看错误日志像是 openjdk 的问题，但是具体看不懂，而且 Android studio 3.6 版本找不到配置 jdk 的地方了，求大佬指教
