bug描述：

uni.showToast等所有的uni.函数都不能用，console.log()能打印，使用uni.navigateBack()，直接回重启app

提供复现工程。看你提供的 log， uni.request 和 app.vue 里都是正常调用的。检查你调用 uni 的地方具体怎么写的，是在 uts 环境吗

win10 环境。
goBack() {
uni.navigateBack();
console.log(‘back’);
},代码很简单的，就这个执行后腿，back能打印，然后返回上一个页面，这个不是直接返回到，是uni-app重启后转到这个页面，缓存的token都没有了
