I have the same problem and the code
bar(randi(400,4,3),'stacked')
legend('A','B','C')
gives me the error: Index in position 1 exceeds array bounds. Index must not exceed 11.
The bars are plotted as they should, but the legend won't appear.
I am using R2022a.
Help would be much appreciated.
edit:
Directly after posting this I found the error. I was using a variable called 'legend' in another script which was in the workspace. Changed it to something else, no it works fine. Wanted to share this stupid mistake, maxbe I am not the only one.

Ran in:
The piece of code you shared works here without any error, see below.
Share the full error message i.e. all of the red text.
Edit - This should be a (gentle) reminder to not name variables or scripts with the same as in-built functions in MATLAB.
bar(randi(400,4,3),'stacked')
legend('A','B','C')
