> Manage User Accounts in Windows - Microsoft Support
Step 2 - Check for Office Updates: Please make sure your Microsoft 365 apps are updated to the very latest version.
Step 3 - As a moderator, I sincerely apologize that we don't have the resources in our lab environment to directly troubleshoot or simulate this specific issue. However, I recently came across a user with almost the same problem as yours. This user outlined a successful method that worked for their account to fix the issue. As mentioned, manually uninstalling updates was also one of the suggested methods. Please refer to the two links below:
Microsoft Word, Excel, etc open then close immediately. - Microsoft Community
Appreciate your patience and understanding, and Hopefully Microsoft will make improvement soon.
