identityservicesd 99-150% CPU. Macbook Air overheating on latest update.

I have tried deleting the file and following the other threads, trying the shift method when logging in, etc. and nothing seems to calm down the identityservicesd eating up all of the CPU and causing my macbook air to overheat.

It just started overnight last night when I’ve never had any issues before.

MacBook Air 13″, macOS 15.4
