I guess you double-clicked in exe file that provides after building in release mode : For Deploy and create Exe output with QT in windows you should follow this way:
put your compiler path in your system path. now you use mingw81_64 you should set it. something like Qt/tools/mingw81_64/bin
copy exe file that provides after building in release mode in one folder and run mingw81_64 cmd (it has separate cmd) and cd to that folder path
windeployqt app.exe
This command will get all dll needs for your app and your exe will work .
if you use qml
windeployqt --qmldir (the path of its directory ) app.exe

我猜你双击了在发布模式下构建后提供的 exe 文件：
对于在 Windows 中使用 QT 部署和创建 Exe 输出，您应该遵循以下方式：
将编译器路径放入系统路径中。现在你使用 mingw81_64 你应该设置它。类似
Qt/tools/mingw81_64/bin复制在一个文件夹中以发布模式构建后提供的exe文件并运行mingw81_64 cmd（它有单独的cmd）
并 cd 到该文件夹路径
windeployqt app.exe此命令将获取您的应用程序所需的所有 dll，并且您的 exe 将运行。
如果您使用 qml
