How to load this project with isaacsim's version being 4.2

[Little-Sayu]

Hi, I appreciate your work. My version of the isaacsim is 4.2. and I wonder how to load your project with this version(or 4.1). Could you give me some hint about where to modify?

Currently we are working on migrating GRUtopia to Isaac Sim 4.x version, majoring at fixing some stability issues.
We will release it once stable.
