GitHub user potiuk added a comment to the discussion: Tasks in a DAG cannot be executed in parallel to find a solution
I tried to reproduce it with your DAG and could not. <img width="1246" height="574" alt="Image" src="https://github.com/user-attachments/assets/65afe2dd-f567-492b-baea-43c71a0d02f0"; /> You likely have a problem with configuration of your system. Maybe you have too little resources (memory/cpu) allocated on your WSL2 instance. Or maybe you have some other WSL2-specific limitations (for example filesystem limitations). Note that airflow only works on fully POSIX-compliant installations - including Operating System and filesystems it uses, so certain combination of those factors might have influenced behaviour of your installation as well. For example if you are using sqlite db and your filesystem is mounted from Windows, I guess this might heavily influence parallelism of database operations. My suggestion is to give plenty of resources to your WSL2, make absolutely sure that you install and use airflow installed only inside your linux WSL2 including all filesystem (reinstalling things from scratch might help).
