Hello! 
The game was updated, which includes updates to the game’s anti-cheat, therefore the trainer and/or anti-cheat workaround needs to be updated.
The game’s anti-cheat is the reason why you need to follow additional steps to get the trainer to work - you will have to complain to Capcom if you don’t like their anti-cheat or the additional steps that you need to take to work around it, not to Wand (formerly WeMod).
Recent information is in the official thread for the trainer, including a notice at the top that an update is required: Resident Evil Requiem Cheats and Trainer for Steam.
