Occupying space and not deleting the backup file

[Reza.alr]

I encountered two problems in version 12.1:
1-Failure to delete the files in the backup path in the management console, which the antivirus has suspected and quarantined, and it cannot clean them, and unfortunately, they are not deleted, causing the system to slow down and take up space.
2-in this path c:\Program data\kaspersky lab\KES.21.14\temp\tempio
inside the folder tempio there is a series of saved data that takes up a lot of space and I can't delete those files
