Do you use the XModules?
IMPORTANT CHANGE with Version 7 : If you use macros that run more than ~2 minutes you MUST install the XModules .
If you do not use the XModules then Chrome will stop the macro after ~2 minutes at a random point in the macro. 
No error message is displayed. The macro just stops. Please note that this behavior is not a bug of our software, but a “feature” of the new Manifest3 Chrome API.
Solution: Simply installing the XModules resolves this issue . The XModules app prevents Chrome from stopping UI.Vision macros 
The other solution would be to use the Firefox version of the RPA software.
