Cannot determine loading status from unknow error

Hi, I’ve been getting this error for 3 days. When I run it a few times without making changes to the process,
It crashes in a different place each time. Sometimes at the beginning, sometimes at the middle or end.
I tried the same project by creating a new process, but the result is the same. Error location variability
I could not figure out exactly where the problem is because it shows.

If you don’t make a change and cannot find one, it is due to the dynamic xpath structure.
