Product export does not work

Hello, thanks for the answer, you are right, the problem was with the mail, the error "IMAP status: Not ok ([AUTHENTICATIONFAILED] Invalid credentials (Failure) Too many login failures)". I already figured out that it was not about export. It's just not clear, because I get a message that the file will be sent to the mail, the error is not displayed anywhere, maybe I can look at the logs somewhere, I didn’t find it .... I found how they fixed the problem with the mail, and solved it through application password. I just didn’t understand why we didn’t change anything with the mail, and the settings stopped working with it. Everything worked yesterday.
