Office 365 Problems

Hello everyone,

I have been experiencing the following problem since today:
As soon as I try to open Excel, Word, Outlook, etc., they close again immediately.
Online repair and reinstallation did not improve the situation. 
Some of my colleagues are experiencing the same problem.
Background: We roll out updates at intervals. The users who were in the first interval are experiencing these problems.
The update interval has been stopped, but unfortunately I can no longer undo the update.
The following version is displayed: Version 2509 Build 16.0.19231.20138.
The computers are running Windows 11 with the 24H2 update.

Does anyone have the same problem or know a solution?

Thanks in advance.
