The same repro steps on 4.26.2 will launch the project successfully.
Packaging a project once to create complete ShaderMaps will work around the issue.
Failed to find shader map for default material WireframeMaterial(/Engine/EngineDebugMaterials/WireframeMaterial.WireframeMaterial)! Please make sure cooking was successful (Contains inline shaders, has GTSM)
