We are both using Windows 10 Enterprise Version 1909. I have a slightly older OS build (18363.1854 updated Oct. 12, 2021) than my colleague (18363.1977 updated Dec. 14, 2021), but it's my emoji artwork that changed, not theirs, so I suspect the OS builds are not the issue. We work for a large company and can't make updates to our operating systems without IT intervention.
