Please install Gstreamer.

Thank you! That previous error is fixed. There is a new error if I switch to shipping mode(Development mode can be built successfully): Missing precompiled manifest for ‘DesktopPlatform’, ‘D:\UE_5.1\Engine\Intermediate\Build\Win64\UnrealGame\Shipping\DesktopPlatform\DesktopPlatform.precompiled’. This module was most likely not flagged for being included in a precompiled build - set ‘PrecompileForTargets = PrecompileTargetsType.Any;’ in DesktopPlatform.build.cs to override. If part of a plugin, also check if its 'Type' is correct.

And I checked the build.cs file, it already has this line of code. "PrecompileForTargets = PrecompileTargetsType.Any"

Any thoughts on why this is reporting error? Thanks

it's a known issue with UE, DesktopPlatform module unsupport shipping mode, you need remove it from your project if you want package in shipping mode.
