Error report: Zotero not starting
Hello, Zotero simply stopped working. (error report 1149682885). The window appears but no reference happens and I get an error message in the main window.

You should move it out of there immediately.
You can try to repair your database, either with the database integrity check in the Advanced → Files and Folders pane of the Zotero preferences or the DB Repair Tool, but we can't help beyond that.
In the meantime, I was able to retrieve my references by selecting a new and empty folder as data location. Zotero then suggests to download the references from my online account, which were not corrupted. It recreated the references locally and I can start afresh.
Thanks for the diagnosis.
