This message appears whenever I want to start working with Zotero, it's also working very slow.

You're a member of a group with over 400K items (including child items). That's extraordinarily large for a Zotero library, and not something we regularly test with. Zotero's memory usage on Windows is currently limited, and it looks like you're hitting the limit with a library of that size.

We'll try to test with a library of that size and see if there's anything we can optimize, but not sure when that will happen. This limit doesn't exist on macOS or Linux, so if you have an option to use Zotero on one of those platforms, that would work better. Otherwise you'd likely need to leave that group.
