Game has been crashing for weeks

I am a pc/Gaming Laptop user.  My game began crashing at random times, then when I was in CAS for more than 3 minutes, now it crashes constantly.  I have NEVER used any mods, so that isn't it.  I have updated my NVIDIA GEForce RTX video drivers, I have unloaded and reloaded the game, I have cleaned every cashe I can find 2-5 times daily.  Now the game is crashing about every 30 minutes.  When I reloaded it said it did not recognize my video cared, but graphics are great.  Please let me know what else I can do.  This is my favorite game, I am recovering from a concussion and I really want to play.

Thank you!  I know you get a lot of hate and frustration.  You see us players at our worst because we have jumped through all the hoops and generic responses, but I really hope you can help me.
