如何在WebdriverIO+Appium+Flutter+BrowserStack iOS环境下重置会话？

我在BrowserStack上运行Cucumber特性文件，目标是重置driver会话，让每个登录测试场景都从全新状态开始。尝试了以下多种方案，均未成功：

方案1：完全卸载重装App（iOS） #

• 问题现象：App能够启动，但无法与设备交互，日志报错500未知服务器端错误

//app starts but cannot interact with device
//[0-0] 2023-11-07T10:37:33.182Z ERROR webdriver: Request failed with status 500 due to unknown error: An unknown server-side error occurred while processing the command.
//Original error: {}
async function fullResetOnIos(){
    await driver.switchContext('NATIVE_APP');
    await driver.terminateApp('nl.abp.app');
    await driver.removeApp('nl.abp.app');
    await driver.installApp(appIos); // 'browserstack.midSessionInstallApps' required
    await driver.launchApp(); //deprecated in logs
    await driver.switchContext('FLUTTER');
}

方案2：关闭并重启App #

• 问题现象：App能够启动，但无法与设备交互，日志出现状态13请求失败、状态200未知错误等信息

// app starts but cannot interact with device
/[0-0] 2023-10-31T08:35:25.289Z DEBUG webdriver: request failed due to status 13
//[0-0] 2023-10-31T08:35:25.290Z WARN webdriver: Request failed with status 200 due to unknown error
// [0-0] 2023-10-31T08:35:08.060Z ERROR webdriver: Request failed with status 200 due to WebDriver Error: unknown error
async function closeAndLaunchApp() {
    await driver.switchContext('NATIVE_APP');
    await driver.closeApp();
    await driver.launchApp();
    await driver.switchContext('FLUTTER');
}

方案3：重新加载会话 #

• 问题现象：执行结果极不稳定，有时测试通过有时因超时失败；一旦某个场景失败，后续场景也会跟着失败

// Very inconsistent, sometimes test execution is green, sometimes not because of timeouts
// When a test fails in a scenario, the last scenario will also fail in browserstack
async function reloadSession() {
    await driver.reloadSession();
}

方案4：终止并激活App #

• 问题现象：被测App停止运行，iOS设备上的缓存未被清除

//app under test stops functioning, caches are not cleared on iOS device
async function terminateAndActivate() {
    await driver.switchContext('NATIVE_APP');
    await driver.terminateApp('nl.abp.app');
    await driver.activateApp('nl.abp.app');
    await driver.switchContext('FLUTTER');
}

除此之外还尝试了其他方法，但都没有效果。请问有没有人遇到过类似问题，能提供可行的解决方案？
