不确定我在应用程序中更改了什么，但我在发布后突然得到这个无法追踪的堆栈跟踪（我更新了一些依赖项，但不确定是哪个导致我无法复制。

All of a sudden on Fabric I started getting a crash report with the below stack trace:

系统规格：

• 视窗11
• AMD 锐龙 9 5900x
• RTX 2080 TI
• 华硕 PRIME x570 PRO 主板
• 32GB内存

Android 模拟器极其滞后（无论选择哪个图像，我都尝试过从 API 21 到 33，并且每个图像都存在问题）。动画不流畅并且在动画时出现很多断断续续的情况（就像它们在当前状态和 1 毫秒前的前一个状态之间跳转），并且随机出现很多奇怪的黑色伪影，我什至无法使用录制功能模拟器（结果只是黑屏）

我尝试过的：

• BIOS更新至最新版本（4403）
• AMD处理器芯片组驱动程序更新至最新版本
• Hyper-V、Windows Hypervisor 平台和虚拟机平台已关闭
• 已安装适用于 AMD 的 Android 模拟器 Hypervisor（通过 Android SDK）
• 使用模拟器图形的“硬件”
• 重新安装Android Studio
• 重新安装 Android 模拟器管理程序
• Windows 没有更新
• 运行模拟器时 GPU 使用率约为 2-3%
• 在工具窗口或浮动窗口中运行模拟器没有效果
• 尝试了模拟器设置中的所有渲染器（即使通过终端）
• 编辑：未安装防病毒软件

• HAXM Enabled版本7.1.0，并且我验证了模拟器运行时它是否正常运行
• 该仿真器正在使用Nvidia GPU，但在任何给定时间都几乎不使用最大7％的GPU
• 我有27.3.1的仿真器版本（最新）
• 尝试过x86图像和x86_x64图像
• 我尝试了硬件加速
• 我尝试了软件加速
• 我将模拟器的内存提高到了4GB（我有20 GB）
• 我将仿真器CPU优先级设置为实时
• 我有一切，但正在运行Android Studio和模拟器
• 从活动转到另一个时，仿真器的运行速度极其缓慢且缓慢，甚至出现黑屏
• 永远都是这样
• 我尝试删除整个Android SDK并从头开始安装
• 我在BIOS中启用了英特尔虚拟技术
• 我尝试过Google Apis与无Google Apis模拟器
• 我尝试了带有Android P，O，16的Nexus 5，X，Pixel 1、2，XL和所有笨拙的设备

这是堆栈跟踪：
