UE Plugin development intelligence not working.

Could it be you need the Index Plugin option on, under Languages & Framework/C++/Unreal Engine?

Hello Cesare,

Thank you for contacting Rider support. 

Would you mind trying the following steps and letting me know if it helps?

• Ensure the option "File | Settings | Languages & Frameworks | C++ | Unreal Engine | Index plugins" is enabled;
• Restart Rider;

Hello Robert,

Would you mind ensuring (Help | About) that the Rider version is greater or equal to Rider 2022.1?
Have a nice day!

I have the same issue but I do not have such option in the settings as Ruggero Riccobene mentioned.
