The project is not working anymore after updating to UE 5.5.4

Hi there My project is not working anymore there is a blueprint error


How do I solve this? If I try to replace or refresh the nodes it crashes

Hello @info2,

Welcome to the Convai Developer Forum!

From what I can see, it appears that your project contains customizations, and the errors you’re encountering don’t seem to be related to the Convai plugin itself. These issues are likely tied to your own project setup or blueprint structure. We recommend that you review your recent changes.

I have done not custom changes. All the projects that were working now they have this errors.

It’s possible that the Convai plugin files may have been modified or corrupted. We recommend reinstalling the plugin to ensure everything is working as expected.

To do this:

  1. Open your Unreal Engine Library.
  2. Under version 5.5.4, click Installed Plugins.

  1. Locate the Convai Plugin and click the Remove button.

  1. Once removed, re-download and install the Convai Plugin.

This should help resolve any issues caused by corrupted or altered files.
