@Ben Snape , After doing more research, I find, Fresh Start is not the same as a wipe of the PC. The Wipe action restores a device to its factory default settings. While Fresh Start can retain personal data. The main intent of Fresh Start is to help improve performance and device health. Fresh Start installs a clean, up-to-date version of Windows 10. Fresh Start will remove most of your apps, including Microsoft Office, third-party anti-virus software, and desktop apps that came pre-installed on your device.
I wonder if the process is failed during the office app remove stage. We suggest to manually remove the office app and do a fresh start again on the affected machine to narrow down if it is related.
Please try the above suggestion. If there's any update, please let us know.
