Download the newest UE 5 version because packaging doesnt work?

Hello, I have a problem while packaging my project in UE 5.3.1, i always encounter this error:
UATHelper: Packaging (Windows): LINK : fatal error LNK1181: Eingabedatei “ThirdParty\libcurl\7.83.1\lib\Win64\Release\libcurl.lib” kann nicht ge�ffnet werden.

I read that updating to UE 5.3.2 could fix this problem but how can I update my Engine to the newer version or where can i download 5.3.2?

You can update by opening Epic Games Launcher and going to Unreal Engine → Library → Engine Versions.

If an update is available for a version it should say Update instead of Launch

I dont have the newest Version but i dont have a Update button i can just launch the Engine:
