I accidentally deleted SyncRootManager from the Windows registry

Application Affected
Dropbox
Device
Dell Latitude 9440
Operating System/Browser (if using the web)
Windows 11
Dropbox App Version (if using the app)

 

Question or Issue
To resolve an issue not related to dropbox I deleted this key in the registry:
HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\SyncRootManager

Now Dropbox won't start. I have recreated with Key + permissions using another PC, but it seems Dropbox doesn't have the permissions to install what it needs inside this key. How can I fix this?
