I didn't have the folders:
I did clean up the other folders and re-downloaded the trainer outside CH Trainer Manager.
It was both restarted and had a full shutdown then startup done (Windows 10 doesn't clean the RAM anymore on restart or normal shutdowns, System Settings have to be adjusted to disable fast Windows bootup).
Both the CH Trainer Manager and the trainer are running as Administrator; I've also configured the AV software to exclude the folder that contains both and any executable running from there from any scans.
I still have the crash issues, however, it might be that my save has issues has I have 1 quest that didn't trigger the enemies to defeat...
I can't reply on that topic, so I'll leave a suggestion here, to make that script even simpler, use %username% instead on those paths, Windows will automatically convert that to whichever is the username that is running the script.
Random game bug, it was present in the original as well. there is a link on the steam forums to report bugs to the game dev's.
Usually happens when you first fight the Tuatha and have to use your fate ability, something the game is expecting does not trigger.

I can confirm that - had the same bug once in the original-game back then.
