Outlook shrinks text (inbox)

Hello.

I have an issue with my outlook app - m365 subscription (with windows 10 latest updates).

Some of my inbox emails have a weird form. I can not find out why. I contact the sender and it seems fine with them. I also tried in safe mode with disabled add-ins. Also seems ok. (I have already disable my add-ins). I have tried to repair Outlook, but did not solve the problem. I check the email in an older version Outlook 2016 and it seems also fine!
