qrc:/chalk.qml:2:1: plugin cannot be loaded for module "QtQuick.Particles": Cannot load library F:\package\pp\QtQuick\Particles.2\particlesplugin.dll

I wrote a  program based on Windows platform through QML to achieve the chalk and ash drop effect. Particle system is used in the program.  Although there may be not smooth, it can run normally under debug and release versions and also find the library of Particles.2\particlesplugin.dll. However, when I packaged the application release version with the windeployqt command statement, the application worked but failed to produce particle effects and was monitored through debugview, which show the errors was that qrc:/chalk.qml:2:1: plugin cannot be loaded for module "QtQuick.Particles": Cannot load library F:\package\pp\QtQuick\Particles.2\particlesplugin.dll. I've added the QML folder Corresponding version in the exe package directory, and it found the library, but it didn't load. What's the matter, please?
