在 MATLAB Online 中打开

Try the command below, restart MATLAB and open Appdesigner

restoredefaultpath

In MATLAB, go to "Preferences -> MATLAB -> Web" and see if "Use a proxy server to connect to the internet" is checked. If it is, uncheck this option and see if the issue persists.
If the issue still persists check out the link below: https://www.mathworks.com/support/bugreports/1483341

Thanks for your answer. After step 1 and 2 the issue still persists. For step 3 I will contact our system administrator.

Sure. Judging from the bug report it looks like it was a prevalent issue and by adding that patch providing in the zip file, things should be back to normal.
