Ok, I will try to do this but should I do some backup of INBOX earlier?

I have a problem for specific mailbox. In mail.err file I see a lot:

I have many mailboxes on the server and each of them work perfectly except this one.

Somehow cache files have been corrupted.

You can try to fix them with: doveadm force-resync -u user INBOX

One more thing. I've made a copy of Maildir directory and executed -> doveadm force-resync -u artur@example.pl INBOX. Maildir directory weight 2.6GB. Executing of this command took around 1sec. Is it that fast or I used wrong arguments?
