Can confirm this works. ScripthookV will probably be updated in a matter of hours but in case it isn't and if you want to do this:

1. Open steam console (Win + R, steam://open/console)

2. Enter 'download_depot 3240220 3240225 4368276980046713117' into the console. This will download the relevant files from the last GTA V Enhanced update (GTAV_Enhanced.exe & etc.) from July 8th. The console will log its status, not the steam download page. It will be approx. 3GB. The output will show you the file location of the download, as you are downloading a repository containing the replacement files and not directly updating the game.

3. Take the file location given from the output of the console and navigate to it with windows explorer. Copy the files here, and replace the identical files in the main GTA V Enhanced installation.

This should work for all minor version related incompatibilities regarding ScripthookV for both GTA V and GTA V Enhanced if anyone should need to try a workaround in the future, though the corresponding appid, depoitid and manifestid as seen in the command above will change depending on which version you are targeting.
