Resolve 20 freeze, stuck playback

Hello there!

Resolve 20 (free), sistematically freezes each time i manually move the preview red cursor in the timeline in a, let's say, "fast way". If I'am moving the playhead back and forth for 5 seconds, like i'm going from a clip to another during this movement, and the playback stops.

Black screen plus most of the Resolve interface is stuck, freezed.
I can only manage to exit the program.
In the attachment the playback is stuck on a frame, working on .braw files.

I'm running Resolve 20 (free) on this specs:
- Microsoft Windows 11 Pro 10.0.26100 build 26100
- AMD Ryzen 7 4800H with Radeon Graphics, 2900 Mhz, 8 core
- NVIDIA GeForce RTX 2060, 6GB - Studio driver v. 576.52
- RAM 16 GB ddr4
- 1 tb ssd nvme (half space free)

The ram is always on 60% since i use proxy media.
Never experienced similar problem with davinci 19. Sometimes crashed but not every 2 minutes, like is happening now.
