Mike Norris calls Andy's friends "Millennials". They are Generation Z, not Millennials.

There are numerous Buddi toys involved in the chaos in the toy store at the end of the film, after Chucky hacks into them. It's not clear what happens to them, as Andy and Karen are faced only with Chucky a few minutes later. However, since Chucky has finally cornered Andy, controlling the other toys may no longer seem necessary.

In the first part of the film, Chucky mistakes Andy's name as "Andy sup" and calls him this. He starts to call him simply "Andy" after a while. Presumably, they either figured out how to change his name as one can with Siri or Alexa, or Chucky's intelligence grows enough to know to call him just "Andy."

In one scene, the characters are watching a version of The Texas Chainsaw Massacre 2 that's wildly out of order.

When Andy and Chucky jump on the hanging apparatus at the end, it is clear that they are being suspended in mid-air and are not falling after jumping. For Andy to have maneuvered Chucky's knife to cut the rope would have been impossible in mid-air.

Gabe's thermostat should have safety perimeters in place that prevent it from being set at the extremely dangerous temperature it gets set to..

When Shane is wrapped in the Christmas lights and being dragged into the garden tiller, the lights are still on. The tiller would have chewed up the cord from both ends causing the lights to go out immediately, but it was a funny premise anyway.

The beginning of the movie shows a warehouse with the label "Kaslan Factory: Vietnam". There is an AC Transit vehicle clearly outside which operates in the East Bay region of the Bay Area, CA.
