An error caused by imread() function in AppDesigner

I'm using AppDesigner in MATLAB, and whenever I use imread() function inside a button this error message displays:

Error using matlab.ui.control.internal.controller.ComponentController/executeUserCallback (line 335)
Error while evaluating Button PrivateButtonPushedFcn.

Use the debugger to put a breakpoint on the imread line, and run. When the debugger stops, Step that line so that you can see the entire error message.

This is what I got:

Caught "std::exception" Exception message is:
Bundle#166 start failed: Loading C:\Program Files\MATLAB\R2019b\bin\win64\builtins\matlab_toolbox_iofun_builtins\mwmlxcodereader_builtinimpl.dllfailed with error: The specified module could not be found.

One of the DLLs is missing that is needed by

C:\Program Files\MATLAB\R2019b\bin\win64\builtins\matlab_toolbox_iofun_builtins\mwmlxcodereader_builtinimpl.dll

You might be able to figure out which one by using one of the tools mentioned at https://www.raymond.cc/blog/check-what-dll-or-ocx-dependency-files-is-needed-for-a-software/

Chances are that you will have to install either Visual Studios Runtime, or else reinstall part of MATLAB.

Thank you! I restarted my computer and the error is disappeared :) I'll try what you wrote if I get this error again
