Why does Bo Burnham flash on the screen at approximately 13:42 in Inside?

Question

At approximately 13:42 in Bo Burnham's special Inside, the overlay with him as a streamer appears for a frame:

Is this an editing error, or is it intentional? If it's intentional, what might the deeper meaning behind it be?

Answer 1

As explained here:

This plays almost like a glitch and goes unexplained until later in the special when a sketch plays out with Burnham as a Twitch streamer who is testing out a game called "INSIDE" (in which the player has to have a Bo Burnham video game character do things like cry, play the piano, and find a flashlight in order to complete their day).

By inserting that Twitch character in this earlier scene, Burnham was seemingly giving a peek into his daily routine.
