'Error caught in launch task' when attempting to mod FC 25 on PS4

[user020]

Attempting to mod FC 25 on PS4 with Anth James' Realistic Gameplay Mod V3 Free version, using FMT 25.13.9145.35106. Steps to reproduce:

1. Edit FC25PS4Profile.json so that "CanLaunchMods": true,
2. Run FMT as administrator
3. Click FC 25 [PS4] -> Find your game executable (EXE) -> browse to extracted FC 25 PKG with 1.1.0 update applied -> select package.mft inside Image0 folder (same issue also occurs if I create a dummy FC25PS4.exe file)
4. Click Load Game ->Import -> import Anth James' FC25 Realistic Gameplay Mod - V3 FREE 'LITE' VERSION #TU6.1.fifamod ->Launch Game
5. Get the error message '[ERROR] Error caught in launch task. You must fix the error before using this launcher'.

Any ideas why this is happening and how it can be resolved? Thanks.
