Can't use the application, lots of (null)

I don't know what happened, but I can no longer use BTT.
I only used it for window management and three finger tap -> mouse middle click.

Big Sur 11.6, BTT 3.597

I removed some /Application Data folders and it seems the app is finally reset (and usable)
I can provide a debug log if neede, else we can close this topic.
