M1 8GB RAM issue

hello, I bought a 8gb m1 MacBook Pro a year ago and I started working with unreal engine 5 early access. it was always using around 2 gb of ram in a blank project. but recently with new update (5.0.1) im having a lots of issues in terms of ram management. for some reason, the gpu only uses 3.2 gb of ram itself while it was 1.2 before last update.

the following footage is from TPS setup but it makes very little difference. as you can see, unreal editor used 5 gb of ram for literally no reason. in these conditions, the system needs to do swap in order to keep up and i literally cannot do anything. i bought something fro marketplace but I didn’t added them to the project.

any help is appreciated, thanks
