[2023] High end specs - Crashes

Hi,

Since 2 weeks, I play again at FH with my new configuration :
intel 12700k
rtx 4080
ddr5 64go

When I lauch game I have an advertisment : your configuration is less than required....
All my settings are on low, so I put them on high and do a benchmark ( and I have 250/300fps )
And my game crash 1 time per hour or 2 with a message that say my graphic card is not recommanded and too low for this game ?!?
I try to delete game, nothing, delete driver of my gpu, nothing, take old driver from my gpu, nothing.....
If someone have an idea....
Sorry for my bad english and have a good day
