🟢ROSLaunch that Gazebo world that I created via udacity_office.launch.
✅ It’s probably due to insufficient memory. I have migrated the whole course repos to local windows 11, wsl2, ubuntu 20.04, ros, gazebo 11 (classic). Originally i was using VMWare with the ubuntu 16.04 image.
VMware: vmw_ioctl_command error Cannot allocate memory.
