Rpa stuck when json file been deleted

i use file system mode load json and execute fine,but when my program delete finished json file and run next json it stuck and can’t play macro even when i click play marco manualy,but command line will success because it log is

Status=OK
###

and no line executed with it still opened last finished and deleted json in orange color and save button not work,not load new json
and i can’t keep json because it will not work after 10 json in folder because it require to upgrade or it will not load more than 10 files…

This is a strange question, I’ve never used ui vision deleting the json files of the executed macro.

Waiting @admin for suggestions
