2. after uploading, no response for keyboard, after a while WindTerm quit automatically and unexpectedly.

中文：
在文件管理器中，F4上传文件，100多M
上传后，键盘无响应，鼠标转圈，一会后WindTerm自动退出

Reproduce the issue in the Filer view by pressing F4 and uploading a file larger than 100 MB with WindTerm 2.6. Start by checking the application's available crash or diagnostic output after the keyboard stops responding. Done means the upload completes without WindTerm freezing or quitting unexpectedly.
