[Zotero 6.0.13 macOS 11.6.6] database upgrade error

I get a database upgrade error after updating to Zotero 6.0.13

The exact error message is:

Datenbank-Upgrade-Fehler

Error: Error(s) encountered during statement execution: unable to open database file [QUERY: DELETE FROM itemTypesCombined] [PARAMS: ] [ERROR: unable to open database file]
Zotero.DBConnection.prototype.queryAsync@chrome://zotero/content/xpcom/db.js:680:13
From previous event:
ZoteroService@file:///Applications/Zotero.app/Contents/Resources/components/zotero-service.js:346:7
@chrome://zotero/content/include.js:4:14


What are the steps to get the database up and running again?

That means Zotero can't open the file. What happened between the last time you ran Zotero and now? Do you have your Zotero data directory in the default location, or have you moved it?

Generally this would indicate a problem with file permissions with your data directory and/or the zotero.sqlite file within it. If you don't think it's that, try restarting your computer.

Hi dstillman,
I have been able to solve the problem. But as always, thanks for your rapid response.

Here's what cause my problem, and the solution:

The problem was caused, because my main drive was running out of space.
After freeing up a few gigabytes, Zotero opened up just fine.

It was not a file permissions problem, and I hadn't moved the data directory (it's in the default location).
