你的代码中没有引入 `filedialog`,所以很难确定具体原因。但是,在你的代码中,没有直接调用 `filedialog.askopenfilename()`,所以很可能是其他部分的代码和 `filedialog` 产生了冲突。请检查你的代码并确定是否有其他部分调用了 `filedialog.askopenfilename()`。另外,检查你的代码是否正确导入了 `filedialog`。如果你仍然无法解决问题,请提供更多的细节和代码,以便我能够更好地帮助你。

可能是以下原因导致摄像头不动:
1. 摄像头没有接好或者连接错误,需要检查摄像头连接是否正确。可以尝试更换USB接口或者更换摄像头试试。
2. 摄像头的驱动程序没有安装或者不兼容,需要安装或更新摄像头驱动程序。
3. 摄像头被其他程序占用,需要关闭其他占用摄像头的程序,或者重启电脑后再尝试启动摄像头。
4. 摄像头硬件故障,需要更换摄像头或者修理摄像头。
