Re: How to fix routined process issues on macOS Ventura?
Could be any one of several reasons why, so without pin-pointing the cause, the solution could also be any one of several possible.
Wondering if you have any un-necessary third-party (non-Apple) apps like virus-checkers, ad-blockers, cleaners and the like installed. If so, try turning them off (or use un-installers from their developers.) Even necessary third-party apps may cause issues if not kept updated to the newest available compatible version.
You may want to check that your Mac has enough memory / storage space free for the tasks you want it to perform. Eg: A Mac generally needs around 50 Gb free in order to operate smoothly.
If nothing above helps ...
There's an older thread using an older MacOS that did troubleshoot a similar issue:
