project requires the 'Traffic' plugin, which could not be found

This project requires the ‘Traffic’ plugin, which could not be found. Would you like to disable it and continue?

If you do, you will no longer be able to open any assets created with it. If not, the application will close.

Hello there @AbdulRehman-745 !

We may require more context for the issue you are dealing with. Yet, it sounds like you are working with City Sample as a base, since that’s where the Traffic plugin comes from. If this is the case, a similar scenario was encountered in the thread below:

I am trying to run the City Sample project but it keeps coming up with a message that the Houdini Engine Plugin is missing. If I continue it also informs me the Traffic Plugin, city sample mass crowd plugin, the HoverDrone Plugin, the Soundscape plugin and the city sampler sensor grid plugin are all missing. Can anyone help please.

In short, re-downloading the project should restore the missing plugin. Alternatively, you can check “C:\ProgramData\Epic\EpicGamesLauncher\VaultCache” for related files, the plugin could be present there. If so, restore it to its former location, and re-open your project.
