I am new Alteryx user, in the workflow I used Alteryx to build my school project.
However I have run into a very weird issue, the workflow will stuck when I process I am processing the 12 file together. The workflow initially made a little progress and then stuck there forever (at least 5 Hour before I click stop)

However, if I only process 4 input at each time, it goes without any issue. Each set of 4 file taking about 3 minute to run, in total it's 12 minutes to run 3 workflow individually. I am using 8CPU 32CPU EC2.(t3a.2xlarge)

Excel files are ranging from 276 MB to 16MB

Here is my workflow attached below
