I've updated to 3.3.5 less than an hour ago and that's what I found for now. solving the 2d world crash by open an old template, remove the current world, add a new 2d world, open it, close the template and then open your project, these steps must be done every time you open buildbox add new assets crash, I don't know... I have set it here because the support response after several days, here I believe this gonna reach them very quickly
Hey there! Can confirm we received your ticket into support earlier this morning. So far having trouble reproducing these on either Windows or OSX. Might recommend an uninstall/reinstall but regardless will discuss more details via your support ticket
