Serious bug caused by plugin installation!

After today’s update, the plugin is ready to install. But a serious error occurred, which prevented Rebuild! I have reproduced this error on two computers.
A normal Unreal5, when any plugin is installed, will the volume of the Epic Games\UE_5.0\Engine\Binaries\Win64 folder drop sharply from 2.71G to 2.11G? ? ! ! All of the “UnrealHeaderTool” related items are lost, making it impossible to Rebuild! This bug wasted me 5 hours looking for it! Because of the repeated uninstallation and installation of Unreal5.

The UE_5.0\Engine\Plugins\Marketplace folder must be deleted, otherwise the rebuild will lose the files.
