launchctl unload doesnt work anymore under sonoma 14.4.1

[fxfactorial]

like:

launchctl unload -w /System/Library/LaunchDaemons/com.apple.newsyslog.plist

errors with

Unload failed: 5: Input/output error
Try running `launchctl bootout` as root for richer errors.

I am getting the same error:

Warning: Expecting a LaunchDaemons path since the command was ran as root. Got LaunchAgents instead.
`launchctl bootout` is a recommended alternative.
Unload failed: 5: Input/output error
Try running `launchctl bootout` as root for richer errors.

It seems unhappy with unloading any LaunchAgents.

Is that it? Totally impossible now to control what daemons can run on macOS?
