Also add what you already tried so far.
so i update my window 10 recently. when i go into fivereborn i noticed line on top, not a big. after a couple sec i get a error like the pic above. once in a while i get "ros launcher process failed before it could give all clear" also. so i uninstall everything both gta and fivereborn. i redownloaded everything and still having the same problem
fyi i am computer challenge lol
