Err20 on all three of my R5's

[OakandGold]

Hi all. I'm at my witts end with these cameras. Im a full time wedding photographer and I have 3 R5's. I am getting the err20 on ALL of them. And they all are only around a year old. They have nowhere near the amount of shutter clicks that should cause the shutters to fail. It seems almost as if they're getting stuck. Its weird. 

I only use canon RF lenses, only use canon batteries, do not use any sort of 3rd party anything on them. I have also updated all firmware on the cameras and lenses. Still, Im getting the errors. 

I have been a lifelong canon user. From rebels to all of the 5D ones and now the R5s. I absolutely love these cameras but I cannot trust these cameras at this point. I had to rent a camera at my last wedding. Which is ridiculous since I spent close to 12k on these. 

Any suggestions? I guess I will have to send them in but after spending this money on these and them ALL failing within the first year is absolutely unacceptable.

I'm out of options.  It could be a production run issue.  I'm not sure what Canon's sigma level is for the EOS R5.

Time to send at least one unit in to Canon.  Perhaps you'll find you need to send the others in as well.

What are the shutter counts?

Hello, were you able to solve error 20 on your R5 cameras, I have the same problem, I changed the shutter and the stabilizer and it still shows error 20, my last option is to change the sensor but I don't know if that will solve it, thank you for your Answer, excuse my English, my native language is Spanish.
