Dataprep engine crashes when performing union on multiple data sources.

When performing a union on 8 datasets of 518 columns and a 2.6M records in total, GCP Dataprep crashes with a null error. It works if I select each source one by one. Each set is about 1-12 MB in size.

It seems to work fine when disabling "Auto Align"
