Stuttering in the playback/timeline so badly I can edit the video

I saw another post but I couldn't fix my issue.
CPU: AMD Ryzen 7 5800x
GPU: Radeon RX 6900 XT
RAM: 32GB 3600Hz
3 SSD 1x2TB - 2X1TB
Windows 10

Reinstalled the HitFilm Express and now the stuttering doesn't stop, and sometimes the application crash, previously with the old version, everything was ok.

I check new drivers and updates for windows and GPU.
I also reinstalled drivers just in case as well the Hitfilm software.

I lower the quality of videos at 1080p 60FPS and still stuttering is constant, before e I was able to work on 4K with no issues at all.
