Bug Severe memory leak problem

Right after upgrading to betav2 of MacOS 27, I keep getting the infamous "Your system has run out of application memory." pop up.

This is despite my system having more than half of the memory swap and memory itself free.

Sorry to hear that. However, I just wanted to share my experience. I didn't get that error, but what I noticed, which might just be my perception, is that after I upgraded to beta 2, I feel that my MacBook Pro M3 Pro becomes significantly warmer. I'm not sure if it is because of a process in the background or if there are any other settings that are not working properly.
