Outlook and Microsoft 365 Apps Crashing on Windows Server

Microsoft 365 Apps for Enterprise App crashes out after about 15 seconds.

Some users reported that their Microsoft 365 apps keep crashing on Windows Server after a Microsoft Office update. Each time a crash occurs, the only indication in the event log is a kernelbase.dll module error.

The root cause of the error is that the Office update integrates the React Native framework to support certain features in Microsoft 365 apps.

The impact of this issue is limited to users who have updated their classic Outlook and Microsoft 365 apps to version 2412 (build 18324.20168). To fix this issue, you can try the following methods.
