Task mining data configuration failures

I've recently started learning on the Celonis Academy courses and I'm stuck on the Task Mining sandbox.

There is an error in the data configuration, it keeps failing:

Uploading paquets from my machine seems to go fine:

Yet it is impossible to analyse the recorded and uploaded task mining data, I'm guessing because the data configuration failed?

It has been over two hours since my test tasks were recorded and uploaded.

Does anyone know what is failing here and how to fix this?
