@TheWandererLives From the errors listed in your dxdiag, a driver, probably a critical one, bugged out and Windows's error handler couldn't fix it. The specific error was an access violation, a type too generic to be of much use by itself. Beyond that, I'd need to take a look at a crash dump to (try to) figure out what driver caused the error and what you could do about it.
If you want to upload a couple of crash dumps, open a File Explorer window and enter C:\Windows\Minidump in the address bar. For the last two or three files, right-click them and select Copy, then right-click the desktop and select Paste. From there, you can zip the files together, upload the .zip to a free third-party filehosting site (Google Drive, Dropbox, etc.), and link it here.
As far as the overall health of your computer is concerned, I don't think this is necessarily a serious issue, but I would suggest not running two games at the same time. This is not to say you're doing any damage, only that you're sort of asking for (temporary) trouble like crashes or BSODs.
There's only one dump file. https://drive.google.com/file/d/1qNBAFuMKXyaiq6gB4iqxs_bOfPqtNXFz/view?usp=sharing
