Matlab cannot import data from file

Hi, every time when I try to import data from an excel sheet with the import tool I get the following Error Code:

I want to import a column from an excel (.xlsx) file as a numeric matrix, but Matlab cannot import the data. This Error appears as soon as I select the file I want to import the data from. I tried different files (.csv files don't work, too) with different names and none of them works.

I've used Matlab for the last time a few weeks ago and everything was fine, I didn't change any settings in Matlab or on my Mac. I know I did a software update on my Mac during this time to Big Sur Version 11.3.1. And I've already reinstalled Matlab.

Any help will be much appreciated.

Could you provide the code you're using for importing the file to check for possible errors?

Hi Andreas,

This issue can be resolved by updating to MATLAB R2021a Update 1.
