Hi Will, this is Bryll
Thank you for writing us here in Microsoft Community.
Version 2310 (Build 16924.20054) seems to be under Insider program preview channel. If your Excel application is running in Insider preview channel, you might want to try switching out of the Insider preview channel.
To effectively switch Excel out of Insider preview channel, you may need to perform manual uninstallation of your Microsoft Office suite: Manually uninstall Office - Microsoft Support
Once successfully uninstalled, restart your computer then reinstall your Microsoft Office suite.
Important note: Make sure you have your product key or account information ready before you do this. You can download the Office setup file from your Microsoft account website or use the media that came with your purchase.
Once Excel is reinstalled, to make sure it is running on Regular update channel, you might want to try this strategy:
- From Windows Start menu, locate Command Prompt then right click to run as Administrator.
- In Command Prompt running as Administrator, type or paste these commands then hit Enter after each:
- cd %programfiles%\Common Files\Microsoft Shared\ClickToRun
- officec2rclient.exe /update user updatetoversion=16.0.17029.20108
