Does the problem persist after closeing and reopening Matlab?

Sharing the entire error message printed to the command window may be helpful.

在 MATLAB Online 中打开

I wonder if your path is corrupt.

which uiopen
% C:\Program Files\MATLAB\R2019b\toolbox\matlab\uitools\uiopen.m

The command above should show the location of the uiopen function. You could search your program files to confirm that you have that file.

xlsread('files','range') : Just to be clear, you have an xlsx file named "files.xlsx", correct? Because the filename input assumes the extension if it's not provide. Also, is the 2nd input a xlRange or sheet value? If it's a sheet value then it's fine as long as there's a sheet named 'range' but if it's supposed to be an xlRange value, then the input is incorrect.

Nevertheless, I don't know what's causing this error. Is this the only time you receive this error?

Have you tried using readtable instead?
