我无法在 Appium 桌面服务器上启动新会话。我还没有找到任何适合我的修复程序。这是我的错误消息：

编辑，已解决： 多亏了罗斯，我找到了问题所在。 我通过将ANDROID_HOME和JAVA_HOME的路径从C:Program Files更改为C:PROGRA~1解决了它，就像这里所说的那样。
只需以管理员身份运行appium，您的问题就会得到解决。我也面临着同样的问题。我已经搜索并知道无需更改路径变量地址。
请按照以下步骤操作：
- 以管理员身份运行应用程序。
- 在启动服务器之前，单击选项"高级"，并选中"允许会话覆盖"。
此问题可以通过正确设置所需的功能来解决。通常我们将 automationName 指定为 uiautomator2。当我们纠正这个错误的那一刻，就会抛出这个错误。
确切的所需功能是这样的，"automatorName"文本"UiAutomator2" 还有另一个属性用于跳过 Appium Desktop 中的签名过程。
"无符号" "真">
将这两个所需的功能一起使用，它将正常工作。
