I can confirm, I have exactly the same problem. CPU hast a permanent load of 58 to 60%, after upgrade from 6.4.0 to 6.5.3

Seems to be an issue with optical devices, If you use VMware and there's an optical device configured (CD/DVD rom), delete it or change its setting (virtual device node) from IDE to SCSI.
That helped for me.

My experience on this topic turns out that when you install kali purple on a clean VM, it is installed with kernel 6.3 but when you apply the command sudo apt update && sudo apt full-upgrade -y the system updates to kernel 6.5, generating a conflict of performance (system slowness), use four types of solutions:
1.- within the VM in advanced options choose kernel 6.3 instead of 6.5
2.- remove the CD/DVD device from the VM to use kernel 6.5
3.- if we need to use the CD/DVD then change the CD/DVD configuration from IDE to SATA or SCSI to use the 6.5 kernel
4.- do not update the system so that it only works with kernel 6.3 while they correct the problem

The solution I used was 2, and the system runs smoothly for me, the tests I did were in VMWare 17 and VirtualBox with Kali Purple and Parrot systems giving the same readability result, which were solved with what I mentioned above.
