photoshop run slow with Ryzen 5 3600 & GTX 1660 & ram 16g

Hello friends
I have a big problem with Photoshop, it only appears when working with large files and sometimes with files that have many layers even if their size is small, as well as when copying Artwork from Illustrator, where it happens very slowly and the editing process becomes very boring, this appeared with me in 2020 version and 2021 version.
Knowing that the specifications of my PC are not bad and are as follows:
Ryzen 5 3600
B450 AORUS ELITE
GeForce GTX 1660
ram 16Gb 3200 MHz team t-force
Crucial P1 500Gb 3D NAND NVMe PCIe M.2 SSD
Western Digital 1TB Blue
