Unable to Start a virtual controller/unpack Pack & Go succesfully

zl522

My RobotStudio suddenly can't launch any virtual controller (which previously worked fine); I'm using RobotWare version 6.10. 

I've attempted the following measures without success: 

1. installing the latest RobotStudio
2. creating a new VC, which also failed to start
3. uninstalling recent Windows updates
4. turning off the Windows Defender firewall
5. and repacking the previous Pack & Go. 

While I try unpacking a Pack & Go file, the window displays 

"Failed to restore backup from %VC name%. Restore failed for one or more controllers in the Pack & Go file. "

"Please try to restore the backup manually, or unpack again using a RobotWare version that matches the original." 

RobotStudio .NET exception: C0040403: No response from controller. Netscan timeout
Base exception: RobApiException C0040403: No response from controller.

While I tried to launch a previously working project, an error message appeared stating,

 "There was a problem when starting the virtual controller. 
No response from controller."
