Premiere pro have glitches and slow play/export, preview

Hello, 

Can you please assist us, we have a problem with Premiere Pro and other video and animation products. Takes long time to load video and it keeps lagging when i play it in Pr.

We have a good PC, and our configuration is as follows:

- CPU: AMD RYZEN 7 5800X 8-Core processor 3.8GHz
- GPU: AMD Radeon RX 6700 XT
- RAM: 64GB

Is this good configuration for use of premiere pro and other video editing programs. Could it be that we didnt set up the programms configuration correctly?
