Microsoft apps not opening after Ui 7.0 update

[Members_Kk3MJuo]

I updated my phone to the lastest UI 7.0 and now my microsoft office apps won't open. They open for about a quarter of a second and then close. 

Now I know there is a fix by using the old microsoft mobile app. Opening that and agreeing access rights to storage.

Which I did. And everything worked.

Though I got a message to say this app is no longer secure and to use the office 365 app instead. So stupidly uninstall the old microsoft mobile app and then everything stopped working again. 

The old app is no longer in either the Google or Play stores and I don't have access to my old phone to use Samsung switch to side-load 

I've tried all the usual clearing data, cache, uninstall and reinstall but no luck. This is absolutely ridiculous how you need an old app to make the latest ones work

Same or similar issue. Most Microsoft apps will not load since update to UI7

Same as you...S23 Ultra + Ui 7.0 - Microsoft mobile applications = -_- disaster!!!!! Tried all the restoring procedures suggested by Samsung assistance and Microsoft,  no turning point.
