Strange Red-Wavy-Underline in Solution

Sorry if this's a stupid question, I'm just at my wits end.

Look the pic below, how weird cuz' the project has nothing wrong with Building/Compiling/Running.

The version is : "Rider for Unreal Engine"

Besides, the build log has native language characters, I want them to be displayed all in English so I can google the error more conviently, how can I modify that ?


Any help will be highly appreciated, thank you so much :D

Could you please call "File | Refresh Rider project" in Unreal Editor? Are there any errors? Does the issue persist after this action?

As for the Build, the build console output in Rider returns the same content as of running dotnet build manually, which relies on a system locale settings. Please take a look at One can try one of the ways to work this issue around - (for example adding PreferredUILang property into a proj file).
