False errors in Rider 2025
Build #RD-253.31033.136, built on February 19, 2026
After I updated a project from UE 5.4 to 5.7 and Rider from 2024 to 2025, Rider 2025 started to show false errors like:
Cannot resolve symbol 'remove_reference_t'
in UE_LOG(LogTemp, Warning, TEXT("Data Asset is null"));
Or 'Class Template Argument Deduction failed'
in `TArray{RootPoint};`
Or Cannot convert rvalue of type TSharedRef<FPCGCreateFloorElement> to return type FPCGElementPtr
in return MakeShared<FPCGCreateFloorElement>();

Is there Clang configure issues or something? I use Linux.
I see some errors in Engine's Array.h
using USizeType = typename std::make_unsigned_t<SizeType>;
Cannot resolve symbol 'make_unsigned_t'
I opened my 4.7 project copy and built it in Rider 2025 with no errors in editor.
Hello,
The is a known problem affecting UE5.7 on Linux: RIDER-130498 Linux grammar checking error, looks like std types not recognized in 5.7
It is fixed in 2026.1 EAP 5. Also, there is a workaround Rider 2025.3 mentioned.
Hope that helps. Have a nice day!
