Strange behavior from i7-12700K

I've just started with Einstein@home so i'm not overly familiar with it. I've decided to start with a new build and i'm seeing some strange behavior. I've got an i7-12700K CPU with 32GB of DDR5 RAM and just a crappy GeForce 210 card as I don't plan to do anything GPU with this system. It's running Windows 10 with all updates.

As for the weird behavior, when BOINC starts up, it runs 100% across all 20 threads for about 50 seconds and then just four threads continue at 100%. The rest all go down to pretty much zero. BOINC still says that all 20 threads are running but task manager shows just four going, the last four - CPUS 16-19. I've rebooted a few times and get the same thing.

I've changed my E@h computing preferences to the maxmimum preset already.

Not sure if there's something up with the CPU scheduler or what.

Any help would be most appreciated!

Here's my BOINC event log:
