May I know which phone model you use?
I use S22+ and in the Settings --> Advance Features, it's possible to toggle on or off Bixby Routine feature.
If you are talking about toggling individual routines on or off, instead of a toggle, there is an option to disable/enable a routine.
Hope this helps.
@NinjaRanga , @tajsingh ,
have you already reported this issue in Samsung Members app? If not, please do so: Samsung Members app > Error report and don't forget to attach the log files.
This will certainly help to solve the problem more faster.
