After finishing process Studio stays in "only read" mode for hours

Scenario: Export several excel reports - control row agains defined rules. It will be 19 reports that contains between 4 and 7000 rows. Controlling each row and then go to next in a loop. If the row don’t meet defined rules it is added as row to a datatable and in the end saved as a new excel file for manual control. After all excel files are controlled and the process is done Studio stays locked in “only read” mode for hours.

Steps to reproduce: Running the workflow

Current Behavior:

Expected Behavior: Should end process

Studio/Robot/Orchestrator Version:

Last stable behavior: 2017.1.6522 (it is started from Studio)
Last stable version:
OS Version: Windows 2012 R2
Others if Relevant: (workflow, logs, .net version, service pack, etc):

Recheck all the wait times added in the workflow/activity. Also check the logic used “for each row” if its not going in for the infinite loop. Would also recommend to check with the same flows on a smaller data and minimum 1 report. Then gradually increase your data in excel and then add another reports to identify when it goes in Coma for hours.

Thanks for yout fast response. I have checked with smaller data and reports, this works fine.

It looks like it work through all the report, but when done with the last one and it is saved things stop.
