Meta Avatars not showing on PCVR build

Hi. I have been using Meta Avatars SDK (v35.2) and Meta Packages (core, interaction etc v72) with Unity 6 and URP. In editor everything seem to work ok, but when i try to build there is no rendering of any avatar. The log files are pretty much the same. The same happens with all Configuration Files given, and even if i create my own configuration files with lit shaders, again no render. Has anyone seen this error?
