Outlook autofill goes off the window, need help fixing it

Hello ! Emails autocomplete goes off the window, how should this be fixed, I've never seen anything like this happen

This is how it looks



This is how it should be like.

It's a bug in a Microsoft 365 update which has been reported to Microsoft, with a potential workaround:

Outlook 2016 Autocomplete is doing something weird


The response to this report shows how to roll back to the previous Current Channel version if necessary:

Outlook 2019 Address Autocomplete Broken

(From Version 2104 (Build 13929.20296) of April 29 to Version 2103 (Build 13901.20462) of April 23)

Thank you !
