Hello,
Do you see any extended error messages in CloudTrail? When you open the project you will see an API call for "StartProjectSession". If the project crashes at the recipe validation step then you should see an error message in CloudTrail for the "StartProjectSession" event, hopefully one that is more extended to what you see in the Databrew console. There may also be some other related errors from other events around the same timestamp which might offer an insight in to the root cause.
You can also see this previous post which may be useful.
Failing this I would suggest raising a case with AWS Support, as we will need access to information from your account which is not publicly accessible.

It seems like the tool only create a little cut of 500 lines of data when you create a project. But in reality my data has millions of lines in total. And when the recipe validation test goes on, if he fails to find a single record for a filter , it returns an empty csv , which create the error when i open my projects. That is very annoying coz, it pick up 500 to 5000 randomly from data source. How am i supposed to open my projects if it can deal with the fact that yeah sometimes i will have empty csv coz none of the tiny 5000 lines correspond to a single filter or join ...
