Unrecognized field name "matlab"

I have a small function that has been running well at first, but now as I am using debugger on it, I receive the following error as soon as the debug point is reached:

Unrecognized field name "matlab".

Error in internal.matlab.datatoolsservices.WorkspaceListener>@(es,ed)evalin('caller',cmd) (line 384)

foo = @(es,ed)evalin('caller', cmd);

It does not seem to matter where in my code the debug point is reached. The same error message now pops up every time I write anything into the command line. If I remain in debugger, the error will occasionally reappear under unreproducable circumstances.

It will appear one last time as I leave debugger and then it no longer appears.

This happens with different scripts as well, so it does not appear to be a specific issue of the code I wrote.

Could you please share the reproduction steps and the version of MATLAB you are using? This information will assist me and other contributors in providing you with better support.

The Version is Matlab 2022b and the reproduction steps seem to be just the regular use of debugger. Put a debug point somewhere in the code and the error pops up as soon as the debug point is reached, as well as any subsequent time I type anything into the command window after that while still in debug mode.

Hi Jan,

in case you are still encountering this problem:

If you have not done so, restart MATLAB.

When you encounter the problem, check if any of your files are called "internal":

which internal

If any files are reported by this, please change their names.

If this does not help, consider contacting the Technical Support team.

Best wishes,

Harald
