As I remember in one of my cases, the Studio 23.4.x had a high memory consumption, and I think also a memory leak in some specific scenarios.
Starting with Studio 23.10.4, I think there were some major improvements for Studio memory consumption.
Can you try to upgrade the Studio to these versions and observe if the memory consumption is better while working in your Studio project?
