Very slow loading/saving savegame (30 seconds freeze)

With my pc version of FH5, when the game is loading or saving a savegame, the moving circle in the lower right corner stops moving for 30-40 seconds, like a freeze.
This very slow situation also happens everytime I change a car in my garage, or when I buy a new car and it’s very annoying.

Another strange thing: sometimes when starting game (after the slow loading) the game didn’t load my last car, but it gave me a car I was driving many hours before. Why? Maybe is the savegame corrupted?

UPDATE: maybe it’s not a corrupted savegame. If I turn off raytracing option, the loading is very fast without freeze! AMD 6800XT, with last AMD driver 21.11.1
