Packaging Fail | UE 5.1 Windows | Build for Linux platform

Hey! I’m trying to build a project with the Cesium for Unreal plugin for the Linux platform, but every time I get a message about a build problem. Below I will give the lines from the Outputlog and from the build log. I will be grateful for help!
Plugin last release from UE Marketplace

Outputlog:

Binary configuration Development

Hi @xp404,

For reasons that are unclear to us, Epic’s Marketplace build process continues to fail to build Linux binaries for Cesium for Unreal. If you’re cross-compiling for Linux from Windows (as it appears you are), you can use the Cesium-built version available from our Releases page, which includes the necessary binaries:

Uninstall the Marketplace version, and then download the appropriate ZIP from above and extract it to C:\Program Files\Epic Games\UE_5.1\Engine\Plugins\Marketplace.
