I have an angle that people might want to consider. I’ve been plagued for this for years now. It’s always at the start of a workout and if you can somehow get past it you’re fine. So my theory is this - the cause of some of these issues (probably not all but some) is the issue raised here:
(Can’t post a link in this reply but google “Zwift Stuck in workout mode” and it’s post 82102)
(“t/erg-stuck-in-workout-mode/82102”)
Because I noticed I was in this state on a workout and trying all the usual maneuvers and then at about the same time - the problem went away at the exact same time that my HR monitor re-paired. Which is to say that very often I pair up my HR monitor but then because I’m not warmed up yet (I can warm up inside the workout) the HR monitor drops out - this happens quite often. So I thought OK what if the HR monitor dropping out can lead to this problem.
And in the above linked report that’s exactly what happened. And the last two attempts I made sure that the HR monitor didn’t unpair (just by pressing the monitor against my chest the whole time) and the problem didn’t occur.
It would be good if people could check and see if this is at all a plausible cause. And if Zwift could try to reproduce in their test setups.

I too am having the issues of power being stuck after the first interval. Started last week. I notice it’s OK if there a few power changes in a workout. The problem for me is if there are lots of power charging.
Not sure if my scenario is the same as the rest of this thread or not, there are a few “ERG stuck” threads, so also not sure this is the right one to respond to. Here is my situation…
Twice in the last week I got stuck in ERG mode AFTER the workout completed. Not during. These were both on longer workouts (90 mins or so). So, after the cooldown phase of the workout, when I want to keep riding, the workout completes, and then my trainer is stuck in that super low wattage at the end of a cooldown ramp. In today’s case I had another 5km to go to complete the route I was on, so I basically had to complete a good portion of the last 5km at 85W which is frustratingly slow for my weight.
In both cases after about 8-10 mins the trainer does come back from this problem, but that’s a super slow 8-10 mins on the bike, and at this point there is no way to fiddle with the +/- buttons on the workout because the workout has already completed.

I did encounter this during a workout today. Upon one of the steps, Kickr didn’t adjust to new workout target power and remained in the current step. I also got the ERG Mode disabled temporarily as i stopped pedaling, but it didn’t disable ist. Only a new Pairing of Zwift and Kickr via Sensor Screen could solve the issue.

PS: I’m experiencing a lot more disconnects during the last weeks. Didn’t change anything on my side.
Happened to me today. Was on a 100km group ride. 5 km to the end I lost connection to Zwift. My music continued to play so not WiFi. Screen came back after about 20 secs but RPM would not go past 65. Tried to unpair and pair cadence again with no luck. Trainer was Wahoo Kicker - Companion App and Apple TV
ARGHH! keep getting stuck on 100w! Can’t go above. All sensors reading well.

You’ve seriously been ‘investigating’ this for 4 years so far? Is the conclustion you’re not going to do anything about it?

Thanks
A couple of times now I have finished a workout and wanted to continue riding to complete a route.
When the workout finished my cool down wattage was at about 125 watts and then the KICKR stayed at 125 Watts. Changing gear made no difference. I paused and unpaired the KICKR but no difference. I raised my FTP hoping it would increase the target but no difference

I had the same issue twice in the last week.
After finishing workout I wished to finish the route, but the ERG mode didn’t disengage and stayed on the latest „cooldown” setup, ~70 Watts for me, which made me unable to finish the route in short time window (climbing route).
It never happened before.
Seems it might be connected with the latest Zwift update.

For me most notable is when I do a warmup before a race. I use a custom workout for warmup, en when it ends, and I switch to the race I’m registered for, the trainer just stays in the ERG mode it was last using in the workout.
I have a workaround, which is to turn off the power to the kickr, and turn it back on after 10 seconds. After that it works fine. It’s just annoying as heck.

Issue has reappeared after the most recent game update. While doing a workout Zwift isn’t sending the next wattage target to the trainer.
Happen to me on 11\20\23 I was warming up for a race doing the INEOS warmup and then about six minutes before the race was supposed to start I clicked join the race and entered in the starting pen. The race starts but the trainer is still in erg mode from doing that work out I could only do 150 Watts. I could not get out of it. I was in the race, but couldn’t go above 150 Watts. I had to kill the whole app. To get it to stop. Never had anything like this happen before.

Happened again with game update 1.53 using an iPad connected BLE. In a workout, coach asked if I can I feel good and can hold an interval longer than prescribed in the workout I should pause it and ride it for an additional 10 minutes. I did so, when I went to resume the workout ERG would not re-engage. Some 10 minutes later, at the end of the workout in cool down, ERG message showed on screen telling me to hold steady while it reactivated. It never did.
