Check with Kaspersky support.

In the event that the passwords information is lost, you should record all information in a separate text file somewhere else on your hard drive, or written down. You can easily copy and paste if you need to do so. If you are concerned about someone else looking at that file, you can compress it using a password.

Also, I strongly suggest never using Kaspersky, they are shady at best and often cause more issues than they solve. Keep windows 10 up to date, and use Windows Defender
