I think temporary profiles can't be deleted. Check the folder:
"....\BrowserAutomationStudio\apps\26.7.1\prof"
The reason for this behavior may be that BAS does not have permissions to edit/delete files.
Try to run the program as administrator.
Try restarting the project periodically using the buttons in the interface, but not through forced closing or closing via Task Manager or something similar.
Try moving BAS or the project you are running to a different directory or disk.
