The first 2 errors list missing variables that are added by the initial file patch. If I had to guess, then I'd say that you failed to either do one of these two actions or the order in which you performed them was wrong:
- copy the contents of "Put in Strive Game Files" into the Strive game folder(it should ask to replace stuff)
- delete the "backup" folder before starting the game
The order can matter just as much as doing the correct actions. The simplified order of steps is:
- manually move all files and folders to correct places
- delete backup
- start game and apply mod
- restart game and play
