The error may be due to the Excel COM Automation server. Kill all running Excel processes from Windows Task Manager if any and try restarting the MATLAB and run the script again. If the issue still persists, then try using xlsread in ‘basic’ mode.
Refer to the below link to know more about ‘basic’ mode
As xlsread is not recommended to use in the latest versions of matlab, I would suggest you to use readtable instead.

Reading files in .csv format takes less time compared to reading files in .xlsx format .Even using the readtable in 'basic' mode reduces the time to some extent
