Everything was working correctly, but now I can no longer open my projects because I get the following error: **“Plugin ‘Convai’ failed to load because module ‘ConvaiVisionBase’ could not be loaded.”** I would really appreciate your help, because I’m not sure what caused this problem. ### What happened I originally had an issue with my project after transferring it to a new computer. The new computer was using a newer Convai version (Convai 4.0), and my project was originally created with an older Convai version. I previously asked about this issue in this thread: > [@Unreal 5.3.2 – Convai V3/V4 compatibility issue after moving project to another PC](https://forum.convai.com/t/unreal-5-3-2-convai-v3-v4-compatibility-issue-after-moving-project-to-another-pc/6502): > > What do you need help with? Feature request Installation method Not sure Issue area Blueprint Components Impact Normal - something is not working as expected Unreal Engine version 5.3.2 Convai Unreal Engine Plugin version 4.0.0 Project setup Blueprint Target platform Unreal Editor Where does it happen? Not tested yet Short summary Convai V3/V4 compatibility issue after moving project to another PC What happened? Hi, I’m working on a project in Unreal Engine 5.3.2 that uses Convai and M… Following the recommendation from that thread, I tried installing the older Convai version inside the project’s `Plugins` folder. Unfortunately, that did not solve the problem. Because of this, I decided to set up my MetaHuman again from scratch using **Convai 4.0**. Surprisingly, after doing that, everything started working correctly. Even though there was apparently still an older Convai version somewhere in the project, I was able to open and close the project multiple times without any problems. The MetaHuman and Convai were working correctly. ### The problem appeared two days later … ### What did you expect? The problem appeared two days later After leaving the project for about two days, I tried to open it again, and suddenly I received: “Plugin ‘Convai’ failed to load because module ‘ConvaiVisionBase’ could not be loaded.” I can no longer open the project. What is even more strange is that I have another Unreal project, which was created from the beginning with Convai 4.0 and a MetaHuman. That project is now showing exactly the same error as well. So it seems that this is not only related to the old Convai version that was present in my first project. I also tested a completely new project I wanted to check whether the problem was specific to my projects, so I created a completely new Unreal Engine project using the same Unreal Engine version (5.3.2). The new project opened normally ### Screenshots, recording, logs, or minimal repro ![Screenshot 2026-08-25 205714.png](https://canada1.discourse-cdn.com/flex004/uploads/convai/original/2X/7/761dcdfe2b756e10b44661adb924f906f7d9050b.png) ### I checked the relevant documentation, resources, and similar forum posts before posting. on ### I confirm that I did not include API keys, tokens, passwords, secrets, private character data, private conversation logs, or customer data. on ---

There isn’t a version called 4.0. Could you please check the exact Convai Unreal Engine Plugin version from the Plugins tab and share it with us? ---
