Re: game refuses to open or change map after 1 round...random crashes
Try this post #463 (Of course this post describes how to remove the Nvidia cache, I don't know where the Radeons have the cache, you would have to ask your uncle google) :
+ delete BF2042 folder cache --> (...)\Documents\Battlefield 2042
If this not help then analyze whether the errors with BF2042 originated after some Windows update, if so, remove the faulty update.
Microsoft likes to test its patches on users, so there's a good chance that a Windows update caused your problem.
Also test your RAM with some program. It's possible that you have a mismatched RAM, or you've hit on some junk. Every game uses different calculations, so it's also possible that just your RAM may have a problem with BF2042.
Also check this post, the problem you are describing was very popular, maybe you can find some solution to your problem at this link?

It is unlikely that the reason for the errors with BF2042 is an outdated version of Windows or Bios.
BIOS is supposed to control the components installed in the computer and read them correctly.
Windows, MB and GPU drivers and add-ons such as Microsoft Visual C++ , DirectX and derivatives are responsible for handling the game.
I have never updated Windows and had no problems with games. I only update the BIOS if I want to, for example, change the processor to a newer generation, or there is a bug in an older version of the bios that causes, for example, incorrect support for OC or XMP RAM profiles. I also only update the GPU drivers if the game asks me to, or I have the latest GPU on the market. In my case when I have an RTX 2080S, for example, GPU updates don't make sense because the older product is slowed down in favor of the newer one. It's like that with everything, even phones 🙂.
I used to update Windows 10 offline until WIndows 11, then I gave up on that because every update W10 microscopically slowed down in favor of W11. I encountered the same degradation phenomenon in W7 and older.
