I followed the confluence guide to build staging environment by copying the confluence install and confluence-home folders and updating the config and reverse proxy.
I am using Windows 2016 Server and IIS as Reverse Proxy
Everything seems to be working except for Collaborative editing as when I go into Collaborative editing in admin I am unable to turn it on
This is the errors from the atlassian-confluence log
Anyone able to advise what the error is and how I can go about resolving the issue

welcome to the Atlassian Community!
No final answer but I found at least this error message involved in a bug which is closed meanwhile:
Could you please double check if it is okay with versions mentioned in this bug?
Especially it looks there was a version problem with "Java AdoptOpenJDK" in version 1.8.0_222-10 - but the details are in the bug.
Apart from that there are some older contributions here in Community as to Synchrony.
From just the log I cannot say anything more than that - but a last thought: when you say it is just for staging environment it suggest there must be a production environment around.
