What is this ERG mode?
Every time Mrs does a workout it goes into ERG mode and she can barely rotate it with the increased resistance. Then i tapped the ERG mode on the companion app and i think i turned it off and she was able to ride again.
I dont get it. Is the Snap trainer miscalibrated?
You should try googling this...

Basically:
Resistance Mode - It changes resistance sort of like hill elevation. Harder hill, harder resistance.
ERG Mode - Wattage controlled. IE, if it calls for 200 watts, you NEED to maintain 200 watts. If your at 200W, you start struggling and making 190W it'll think it's too easy for you and it'll INCREASE resistance so that you make 200W. What typically happens is your cadence drops, the resistance gets harder and harder while you're struggling more and more making even less power.
Resistance mode - Riding (Zwift etc) and training. If you want to make more power at a certain resistance you make the wheel go faster.
ERG - Really only useful for workouts where you're targeting a power # in training. The trainer increases or decreases the resistance to make your output the desired wattage. If you go ABOVE the expected power it'll decrease resistance.
We ran into this recently where the assumed FTP by Zwift was higher than actual FTP. Therefore training intervals were way too high in a Zwift workout. If you get caught in the death spiral and you can't spin and get the desired power, pedal backwards and it should reset allowing you to try again.
If you're going into workouts without a true measuring of your FTP, the power expected for the intervals may just be too high for the rider. Or possibly just an off day. Doing the workout in resistance mode solves the death spiral issue, but you'll have to change gears/cadence to get to the desired power output as opposed to just spinning.
For workouts, I like ERG as it makes it brainless. I can watch TV without worrying about hitting power targets. Stay at the desired cadence and the trainer takes care of the rest.
Regardless of the above, you should be calibrating your Kickr Snap regularly. As it's wheel-on it's more susceptible to tire pressure differences.
I'm 3/4 asleep so I hope the above makes sense...
