Does anyone know how to fix this issue? I've tried various solutions, but the error keeps appearing on my console. I deleted all the EssentialsX userdata, but that didn't resolve it either. I reached out for support on Discord but didn't receive a response, so I'm posting here on GitHub. Please help!
