well, i managed to fix my issue. what i discovered, is setting to "run as administrator" doesnt always work unless you navigate to exe itself and enable it there. previously, i right clicked my desktop shortcut for obs studio, and changed the compatibility for all users to run as administrator. this didnt help. but when i navigated directly to the obs32.exe and enabled run as administrator there, BINGO! game capture has started working again for Dirt Rally.
so please pass this along, you need to Run As Administrator DIRECTLY from the exe in the install folder, not from a shortcut or anywhere else
