StandardNotes made unusable by importing large files

[dbabits]

I made a mistake of trying to import from Evernote. Out of 2000 Evernote notes, I was able to import some 164. They include 173 files, some of them large. Now, StandardNote has become completely unusable. Worst of all, I'm not able to delete what I've added, and there were some notes made in StandardNote, that I need salvaged, but looks like I can't. Sync is not working Cannot delete. And cannot use the app to copy away its own (not imported) notes. Windows app, v 3.195.13

Any help appreciated!

Delete Anyway does not work and just hangs
