I'm not OP, but just by the way it was worded. It feels vague and grandstand-y. "
I have noticed" is such a silly way to word what's happening here and it's hard not to imbue underlying meanings to it.
And then "can we talk about how we can address that." More vague, leading statements.
Speak to the facts. "The team / org had to roll back this release, the team does not think there is a process improvement that would have alleviated this problem, and the team relied on you to properly make this feature. Our exceptions of all team members is [...]"
Make it clear:
1. This is affecting the whole team (equally)
2. The team as a whole shares this perspective (it's not just the manager nitpicking)
3. There are consistent and vibrant standards that the entire team must adhere to
4. You are not meeting those standard(s) or necessary actions for success.
5. Offer what you think will fix the problem (if anything)
6. Make it clear this is their chance to agree/disagree
7. Continue to talk it out.
Honestly OP seems like a person who has struggled in his position as manager to properly speak to people, and instead of understanding why there was a struggle simply switched to more coded language.
Most people will see through it and react negatively.
