I changed the CppStandard option, but the compiler keeps failing to recognize the C++20 feature and getting an error. I tried with Visual studio 2022 and Rider IDE, and both IDE showed errors. No relevant options were found in the compiler's project settings. How can I use the C++20 feature on Unreal Engine 5?
Make sure you have a compiler installed that supports C++20. Also, you likely need to rerun the setup.bat and regenerate project files after a visual studio version change.
