Client Computer Stuck In Auto-Isolation

Basically what is says on the tin. I have a client computer that self-isolated due to running malware in quarantine/cleanup error. Removed the offending .exe, updated Sophos, rebooted the PC, ran a new scan, etc. 

However, despite the endpoint client not finding anything on other scans, the computer is still listed as Red Health and stuck in isolation. From reading the Community article on isolation, the only way to un-isolate a computer in this situation is to fix the health status. But since the offending file has been removed with no change in health, I'm at a bit of a loss 

Compounding this is the fact that the user is work from home without admin rights, so I cannot physically access the desktop 

Anyone have a suggestion on this?
