Same on my side, got a AMD Ryzen 5 4600G processor, and an AMD Radeon RX 6600 graphic card, playing on steam.
Tried doing a lot of possible solutions, from closing steam before launching game, to renaming steam api to avoid integration.
Even did a fresh install of the game, a cleanup of my driver, a fresh install on all AMD stuff, no solution worked from all the ones I tested.
As mentioned in a reddit thread, the game CPU use spikes up to near 100%, then it crashes, which is frustrating but yeah...
