It is a multiprocessing issue in your system, possibly due to the WSL2 environment. You could either increase the limit of the open files (as mentioned in your error message) or deactivate the multiprocessing in the codebase (this will make the generation of multi-room scenes slower). To disable the multiprocessing, you can set the argument self.multiprocessing = False. https://github.com/allenai/Holodeck/blob/2a2c3c4c7a675dcb6b3ae5363378addfe1dbb6a2/modules/object_selector.py#L41

Another option might be to increase the limit of number of files that can be open by ulimit -n 2048
