When I try to add citation in Word with Zotero, Zotero freezes right before I am able to add any citation (it happens after I click on the add citation button) or after I choose my citation. In both cases, Zotero freezes and usually crashes afterward
On Sonoma, Zotero 6 will currently trigger a prompt at every startup asking whether to let Zotero access data from other apps. Make sure you're choosing Allow. If you choose Don't Allow, this might happen.
If you're running the Sonoma beta, I'd recommend running the Zotero 7 beta as well, which changes how Zotero and Word communicate to a method that works better on Sonoma.
I always allowed Zotero to access data. I have just installed Zotero 7 beta and the problem seems to be the same. This time, Word freezes and when it does not freeze, Zotero crashes. Here is the report https://justpaste.it/59f31
The thread you posted to was about a crash and is unlikely to be the same issue.
