Selfcontrol permanently breaks iCloud Private relay, even when uninstalled.

[Kokonico]

Summary

I installed Selfcontrol, and after doing so, iCloud relay stopped working. I proceeded to uninstall it, but it stayed broken, and still is to this day.

Background Info

SelfControl version?
4.0.2
macOS version?
installed / uninstalled on 13.6, still broken on 14.
Do you use a VPN/proxy, and if so which one?
No.
Has this ever worked for you on a prior version of SelfControl? If so, when?
Not that I am aware of.
Any other special system setup we should know about?
No.

How Do We Reproduce This Issue?

Describe detailed steps that reliably make this issue show up. For example, "start a block containing 5 websites, click button X, then button Y"

install self-control.
run it.
move to applications (not sure if necessary, but I did so)
close it.
uninstall.

What Should Have Happened?

private relay begins working reliably again.

What would this have looked like if it had worked? What did you expect to happen?

private relay can be turned on and off at will.

What Actually Happened Instead?

private relay continues to be broken.

What did you actually see? e.g. what error messages popped up, what window is showing what text, etc.

self control worked fine, but MacOS told me "some of your system settings prevent private relay from working"

(it also mentions that this can be caused by proxies/VPN's I don't have any of those. I am confident self-control is the issue.

This may be the problem:

install self-control.
run it.
move to applications (not sure if necessary, but I did so)
close it.
uninstall.

Try this:

1. install SelfControl, by moving it to the applications folder
2. open SelfControl and run it on a timer
3. let the timer expire
4. uninstall by moving SelfControl from the applications folder to the trash
5. restart the computer

You have to delete the network interface and add it again.
