ScreenTimeAgent using all the CPU and fans constantly blowing

My laptop fans are constantly blowing and I was wandering what it was about, so i went into activity monitor and saw that the ScreenTimeAgent process is using all of the CPU (around 100%, with occasional spikes above)

I tried quitting the process with the activity monitor (force quit) but can't seem to kill it. Killing via the terminal gives this error:

$ sudo kill -9 461

kill: 461: Operation not permitted

The problem occurred again after restarting.

How can this be fixed?
