zotero 7 & macbook Apple M2

About 3 days ago, my local library suddenly eliminated all my files and showed purely blank. I restarted Zotero but it didn't help.
I checked my online library and everything was right. (it showed 774 items). I checked my local data named zotero.sqlite; zotero.sqlite.bak; zotero.sqlite-journal; zotero.sqlite.1.bak. They are well located in user/zotero folder.
I clicked both automatic and manual restoring botton in Zotero and they all failed. (it showed only 30 items but no file available)
I logged out my account and logged in for times. I still can't recover my library data.

Each time I restart Zotero it will be fine in about 5 seconds and soon be blank. The first image is the application screenshot and the second is the online library screenshot.
