Systems Settings>Privacy&Security "Allow applications downloads from" needs to be set to "App store and identified developers"

Does your account have admin privileges? Look in the System Settings>Users & Groups panel to make sure.

Is each software package you are trying to install claimed to be compatible with Ventura on an Apple Silicon Mac? Recent macOS versions sure can break some plugin installers.

Hard to know what else might be going on.

Any other errors on this system?

Did the Mac boot to normal multi-user or safe mode? (Do you see red text saying "safe boot" on the screen before you log in?)

Is the drive the Mac is booted on the internal SSD or an external drive? Have you added multiple boot installs on the internal drive? Added APFS containers/volumes there?
