Could not call method

Hello getting this error on teleport between worlds from players on PaperMC 1.19-81. The main server version is 1.19 and the proxy is waterfall 1.19-499

Error mentions multiverse inventories and bad skull textures, the only problem is that I do not have any inventory on me when teleporting between worlds and it still generates that error. Also, it only generates that error for players on 1.19.1 clients and not players on 1.19
