Evernote user since 2011 with a lot of data, I'm considering switching to Joplin but need reassuranc

I had problems again today. So I created a support post ici:

Damn, I didn't look. If it happens again I'll be careful.
I don't use OCR, at least I don't think so, I haven't touched much, I had just imported all my Evernote data. It can't be related to the import?
