If you're experiencing crashes in 2K, there are a few things you can do to try and fix the issue. First, make sure that your graphics drivers are up to date. If you're not sure how to do this, you can follow the instructions here.
Next, try verifying the game files through Steam. To do this, right-click on the game in your Steam library and select Properties. Under the Local Files tab, click Verify integrity of game files. This will check for any missing or corrupt files and attempt to replace them.
If neither of these solutions work, it's possible that there is an issue with your hardware or software environment that is causing the crashes. Try running the game in compatibility mode or changing your resolution and seeing if that helps. You can also try temporarily disabling any background programs that might be interfering with 2K. If all else fails, you may need to contact 2K support for further assistance.
