Hey @just, welcome! This is likely due to memory issues during concat. Are you using docker? Default memory is quite limited but you can allocate more resources under ‘settings’ in the Desktop interface. There are now also conda environments that avoid Docker altogether.
Thanks!
Im using Docker, with wsl 2 enabled. From what i can find the memory should be dynamically allocated when using wsl 2. However there’s a performance issue across OS file systems, which likely is causing the problem. I’ll try and set it up on my native OS instead(Win10).
