These screen captures were done right after starting 23.0.1 you can see at the point in time 23.0.1 usage of RAM is under 2GB.

So I have no Idea why they were in there.

I have also ended the task in Photoshop with Tasn manager and Photoshop keeps running and working. I have seen CS6 use up to 30GB on my 40GB machine the max amount of I allow Photoshop to use is 90% 36GB. I have run a large Batch job with 23.0.1 and by the end of the job Photoshop address space was up to 26.1GB. It uses the most started 1.6GB, where CS6 uses around 800MB. This including Photoshop 2022 version 23.0.1. All version of Photoshop I have install will use under 2GB when I first start them and nothing is open in Photoshop. How much RAM any version of Photoshop will use depends one what you do when Photoshop is up and running Whet they need more RAM the will allocate and user in and reuse it and not return it to the system till you shut down Photoshop or use edit Purge to have Photoshop to return some of the resource it has allocated and is not current in need of.
