UATHelper: Packaging (Windows): [Upgrade]
UATHelper: Packaging (Windows): [Upgrade] Using backward-compatible include order. The latest version of UE has changed the order of includes, which may require code changes. The current setting is:
UATHelper: Packaging (Windows): [Upgrade] IncludeOrderVersion = EngineIncludeOrderVersion.Unreal5_0
UATHelper: Packaging (Windows): [Upgrade] Suppress this message by setting ‘IncludeOrderVersion = EngineIncludeOrderVersion.Unreal5_2;’ in TileGame.Target.cs.
UATHelper: Packaging (Windows): [Upgrade] Alternatively you can set this to ‘EngineIncludeOrderVersion.Latest’ to always use the latest include order. This will potentially cause compile errors when integrating new versions of the engine.

ctr+f → error

which means: set a proper icon for your project.

Not every *.ico file is a file in the proper icon format, some are just renamed jpeg or png, which ARE NOT ICONs.
As the simple solution use some online convertor to make correct icon from any source image you have
