Not sure, but this might be caused by whatever Microsoft Office Word is doing on the different platforms.
Office on Windows seems to identify itself as Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/133.0.0.0 Safari/537.36 Edg/133.0.0.0
While Office on macOS seems to be Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko).

Maybe those JS engines are just garbage and don't support pushState and replaceState.

Hi @TheDevMinerTV, thanks for writing in.

Any chance you can check typeof window.history.pushState and typeof window.history.replaceState?

MS Office 365: both are functions

I guess it solved itself? I assume some older Office installs are still based on the old Edge engine which doesn't have this.

I opened #15632 - turns out one of our instrumentation/patching helper functions didn't account for the edge case that the thing to path is not a function (as in this case, undefined or null). While this ocurance in particular is an edge case, I think fixing this class of potential SDK errors is an overall win. Thanks for reporting!
