After ungrade to 25.3, playback is laggy

I'm using Mac Book Pro (I9, AMD Pro 5500M, Sequoia 15.5, PP 25.2.3 build 4)

I have a 2 hours multicam project with AVCHD, Sony EXCam files which are working well without proxy.

After ungrade to 25.3, playback is laggy, and always hang up during dragging time), it does help enen though I used proxy.

I found only 1 AVCHD files, the playback is worst.

So, I reverted to 25.2.3.
