I am currently working with Simulink and out of the sudden, I am unable to change the Model Configuration Parameters.

Whether I try to open the window via RightClick->Model Configuration Parameters or via Ctrl+E, in both cases, a blank white window opens.

This problem persists after a reboot and opening/closing MATLAB. Furthermore, it is the case for any model (whether old, new, untouched, example...) on my computer.

Is there some graphics cache or can you think of another way, how I could get the dialog back? A photo is attached:

Thanks a lot in advance!

This is the form for opening the model configuration interface, and it is completely blank.

1.Try opening via command window or script:

mdl = bdroot;                      % or your model name
cs  = getActiveConfigSet(mdl);     % grab the configuration set
set_param(cs,'Solver','ode45');    % example: change params by script
% show the dialog via API (sometimes bypasses the UI glitch)
try, configset.showDialog(cs); end

2. Delete temporary files (often they are not deleted properly, for some Matlab issues)

--> Normally located in C:\Users\YourUserName\AppData\Local\Temp

3. Switch to software OpenGL (graphics driver issues are common)

opengl('save','software');     % persist setting
opengl info

Restart MATLAB and try the dialog again.

(To revert later: opengl('save','hardware').)

4. Reset Simulink UI/customization caches

sl_refresh_customizations;           % refresh custom menu/toolstrip
rehash toolboxcache;                 % refresh toolbox cache

5. Check for path shadowing / broken path (If you’ve added many folders to the path (toolboxes, student files, etc.), a shadowed Java/HTML resource can blank dialogs.)

% Backup your current path first:
savepath whichpathdef_before_issue.m   % just a backup file

restoredefaultpath; 
rehash toolboxcache
% (optional) also refresh Simulink customizations after path reset:
sl_refresh_customizations;
% Don’t forget to re-add needed folders later, then savepath explicitly.
