Unreal Engine 5.8.1 was released very recently.

At the moment, the Convai Unreal Engine Plugin does not yet support 5.8.1. Support for this version will be added in a future update.

Although an update has already been released that apparently fixes this problem, my solution was to switch the project from BP-only to C++, which means it compiles before the project is deployed, thereby resolving the issue.

Good luck!!

Thank you for sharing the workaround.

However, official support for Unreal Engine 5.8.1 is not available yet.

The update has been released.

Could you please update to the latest version and try again?
