Why did updates to my macOS Catalina app fall off?

Question

macOS

After updating to macOS Catalina, half of the applications fell off, although they were updated to the current version.
Writes:

The "Unity Hub" file cannot be opened because Apple cannot check it for malware.

before that, I performed manipulations with KIS antivirus. Somehow sloppy demolished it. Could it be a problem? Or does the software still not support the catalina version?

Answer 1

rolled back to macOS Mojave. Phew!))
