Hello Avikant Kamate,
This error occurs because in the Basin module configuration you've set the option "Initial Conditions -> Continue from previous simulation" to True, but the simulation cannot find any "previous simulation", thus the error.
If you set this option to False, then the simulation will start with the default initial conditions, and the error will not appear.
You can find more information in this similar post.
Please let me know if it worked and if you have any additional questions.
Kind regards,Luis
