Unfortunately, I can not think of anything more to try. Maybe check one more time if all rF2 servers CustomPluginVariables.json have "Enabled":1 for rFactor2SharedMemoryMapPlugin64.dll, but I think you already did that... Make sure you closing all rF2 and r2la servers before changing json files. Make sure that you are launching everything as a windows user with highest possible privileges. For some reason other rF2 server processes outputs are not available in shared memory. I had similar reports before, it seems that different windows versions have different memory access permissions and stuff like that. I know very little on this system management topic. You can make sure that all your rF2 servers are outputting info correctly by launching every rF2 server separately and see if they work on their own. If yes, then its most probably some specifics with how your Windows manages shared memory.
