this only happens if you go straight to a server.

but if you run a single player instance.. then go back into server it works fine.

Hi there,
I've confirmed the issue - latest release of Data Attributes indeed breaks PlayerEx. Will hopefully release a fix in the coming week.
Thanks.

Fixed with latest releases for Minecraft 1.18.2 and 1.19.2. Curseforge file upload pending approval; available now on Modrinth.
