Word closes completely, I then receive an error from zotero.exe: "Zotero experienced an error updating your document. Would you like to view troubleshooting instructions"

Word version 2011 Build 13426.20332

Yes I can reproduce it. I created a completely new document and after ~2 hours ran into the same error again. I then opened another empy word document and added some citations (ones I have previously used without problems) and at some point i received the error described above.

It causes an entry in windows event viewer. Do you mean something like that?
wwlib.dll is listed as "faulty module" (my OS language isn't English, might be a bad translation), and WINWORD.exe is listed as "faulty application". Event ID 1000, "Application Error".

The PC is equipped with 16GB RAM.

If that's in any way helpful: It seems to be an issue that came with the current version of Zotero. Haven't used it in a few days and i'm fairly certain it updated when I opened it today.

Word crashed the second I clicked "add citation". Shame, that just makes things more difficult.
Same message upon crashing, the ID is 818749560.

Is there any chance this is caused by my current word installation? (vague question I know - just figuring there might be some experience with these kinds of problems) I could certainly reinstall office to debug, but as that would lead to quite a bit of configuration afterwards, I will only attempt it if there's a chance that this resolves the issue.

I just uninstalled the updates that were installed (automatically through windows updates) since Zotero last worked. I have not made any changes personally. I worked with Zotero last friday, so there can only have been so many changes.

No other word plugins are installed.
Disabling Firewall and/or my anti-virus software does not have an effect either.

I have now reinstalled office - and repeated the steps described above - the error persists.

This is worrisome, whether Zotero is causing this or not; I am unable to do anything about it. A spontaneous OS reinstall does not exactly sound like an option but it will probably get down to this. Since the cause is unknow this isn't a promising choice, because who knows if the error will just pop back up.
Additionally, zotero does work for a while when I open a new word document. Somewhere along the way, something just seems to go awry.

Thank you for your help so far, if you have any more ideas I'm wide open.

Follow up on this;
I intended to reinstall my OS and thus started working on another client for the time being - and now I'm experiencing the same issues there, which makes me wonder whether one of the sources in my Zotero library could be problematic? (For the sake of completeness, the Debug Output is below)

Are there steps that I could take to identify a potentially faulty source (and remove whatever causes the issue)?

I installed the Windows 10 language packet and was able to reproduce the error. Though admittedly, that install was rather incomplete; based on the amount of guides on how to complete it that is rather typical though. Should I install the word language packet as well, or were you specifically interested in the impact of the system language change?

As for the other questions:

Does this computer have the same version of Word on it? - yes, the Word versions seem to be identical, Version 2101 (Build 13628.20274)

Did it work well for a while before you started getting crashed? - yes it did, but the error eventually occurs on new documents as well. Sometimes I can add 10+ citations over the course of 3 hours without issues, and other times i have an immediate crash. (I also tried disabeling my anti virus, which does not

Can you reproduce this in a new document too? - as mentioned above, yes I can. I kept a document open (several times) just occassionally typing some text and adding a citation, and after a few hours it crashed. (I save regularly, the file was saved locally, not synched to One Drive)

Hi, sorry for the late answer. I have now completely reinstalled one of my devices, everything is in English. I will post again once I sufficiently worked with Zotero.
