Just updated my M3 MacBook Pro max to the new Tahoe - but now none of my Microsoft apps (Word, Excel etc fail to work). I've since binned these, re-purchased a new 365 subscription today and downloaded / installed and updated all apps, but no - they quit as soon as I open them. Anyone else having this? Currently I'm stuck..

I had the same issue. I contacted apple support, here was their solution: Restart Mac in Safe Mode, relaunch the Apps. If trouble free, then restart again in Normal mode. Safe mode clears the caches and performs systems checks that seems to have resolved the problem for me.
I'm glad I could help. There's nothing more frustrating than not being able to use your documents. And microsoft stopped it's online and phone support for about a week. Equally frustrating and so unprofessional! Probably got swamped with Mac users! Can't somebody think in advance for once?
I have the same issue. I tried the method above, restarting in Safe Mode, opening all the apps, which worked fine (in Safe mode). Restarted in normal mode, and the issue still persists.
The apps won't even open so there is no way to get to "get info."
It is not a universal issue. My Mac has no issues:
Yes I'm still stuck - basically, the apps do work, but I cannot do the auto updates as this then causes the issue.
I've tried all the tips / open with Rosetta etc. but still need a fix.
Ninguna app se abre, todo deja de funcionar aunque intente usar Rosetta.
Thank you chiinagal13. This fixed the issue for me. I was all set to purchase a new subscription to office when all the other suggestions failed. Thanks for taking the time to post.
@chinagal13 looks like this has finally fixed my issues - thank you kindly..!! Currently updating...
