Can't remote install games on 6.72

So, i always install games on ps4 using the iref-use's PS4 remote PKG sender but since i updated it gives me the error FAILED JSON... i already tried using the pink1stools PS4 PKG linker and the modded warfare's package sender 1.2 but none seems to respond when i try to send the game package, i don't know what else to do at this point. any help will be appreciated.
