我已经使用 Android SDK/NDK 安装了 Unity 2019.4。ADB 服务器无法启动并出现以下错误：
UnityEditor.Android.Command.RunWithShellExecute (System.String command, System.String args, System.String workingdir, System.String errorMsg) (at <303ae0e7a8d8441ab049e592bd1e2100>:0)

System.Threading.ThreadHelper:ThreadStart()
我尝试在终端中运行 adb 但它也无法启动。我已经绕过了windows防火墙。它有这样的输出：
* daemon not running; starting now at tcp:5037
could not read ok from ADB Server
* failed to start daemon
adb.exe: failed to check server version: cannot connect to daemon …
