I had a "format bank" command in one of the functions. I removed that and the problem was solved.

Can confirm. I had a similar issue and it turned out a couple 'format long g' commands were the culprit. Definitely a head scratcher but also an easy fix.

Hello!
I understand that you are facing issues while running a compiled application with the exception in thread- "EventMgr Dispatcher" “java.lang.NoClassDefFoundError”.
The "NoClassDefFoundError" error is thrown because MATLAB was not able to locate Java Runtime libraries that are used by the Integrated Development Environment (MATLAB IDE).
There are several possible causes to this issue:
  • The installation is corrupted and there are “.jar” files missing from the MATLAB installation folder.
  • The ”classpath.txt” file is missing references to Java Runtime libraries.
  • One or several internal MATLAB functions are shadowed by custom functions.
Please try the following troubleshooting steps to resolve the issue:
  • Please execute the following commands in the MATLAB command window to restore the search path to the installation default and then try to check if the issue persists:
>> restoredefaultpath
>> rehash toolboxcache
>> savepath
Thank you.
