Thanks to all for the suggestions.
In my case, I noticed that by default the trainer had doubled keys for time stop and another.
I changed keys, did not use the timer option and the boss fight went as normal.
Great to have received so much support so quick by all.
Thanks to all.
I hope others find their solution too.

Since we added options, likely your custom keys or settings are borked.
have user close the trainer, then go here:
C:\Users\\AppData\Roaming\Cheat Happens\Trainer Settings
and delete the file:
70077.xml
Which will likely clear the issue.
The sewer boss fight (William Birkin) does not trigger properly and then the character gets stuck in the room. Deleting 70077.xml did NOT fix the issue, so apparently it's hardcoded into the savegame and I guess I'll have to start a new game ... too bad I was streaming live and now I'm stuck with 10 viewers and have to abort the whole run, that sucks.
PS: This thread is a week old now. I really hope there will soon be a patch that prevents this from happening. I basically can't complete the game after having used the trainer just once. And I'm not really good at this game, so I can't complete it without the help from the trainer.

I had this issue as well where the sewers boss didn't trigger after using reset game clock option, so what I did was just close down the game and the trainer then start the game again loading the save I had before the boss, and not the autosave WITHOUT ACTIVATING THE TRAINER and start the encounter and he attacks again, then I activated the trainer and everything works normally again.
I hope this might help for those who also have this issue
