I receive the message with such a subject daily at 10:20 AM.
It gives me no important information, and it is nothing but garbage in my mailbox.
Turning off all the options for e-mail updates for issue activity have not helped.
Subscriptions are handled at filter level, not in your profile.
Log in as normal, go to "issues and filters" and go to the bottom of the menu for "view all filters". Find the one named in the email (Sorry, I don't know how to do Cyrillic here, but the line includes "have not updated in 12h" in your screen shot), and from the ... menu on the right, use "manage subscriptions"
You should be able to delete the subscription, or, probably more useful, tick the "do not send if empty" flag
