A few weeks ago, I spotted this, when I went to apply updates to Office 365 ProPlus on my work laptop:
Has anybody else in the English-speaking world seen this when installing #Office365 ProPlus updates? pic.twitter.com/8VcC5bMkPU

It had me confused, but Colin Powers (@iamcolpow) pointed me to a Microsoft Community forum post with a potential fix.
I changed the language order in my Office settings so that English was the first option after Match Windows. Whatever was causing Windows to fall back down the list then went to English rather than Arabic.
Now I can read the dialogue boxes on my Office updates!
