@futurebird not a teacher, so take with a cup of salt, but maybe having them not coding during your speaking parts could help?
Like, locking their screens or all looking at you rather than typing at the machine.

My guess is that anyone calling out like that got distracted with the coding and was not strictly paying attention to what was being said, so when they get the error, they may not see or hear anything aside from the error in front of them.
