warndlg() and msgbox() not passing string

Hello,
All of a sudden, warndlg() and msgbox() don't pass the string.
If I type
warndlg('My Warning','Title')
the dialog box has the correct title, but no warning icon and no message! Same with msgbox()
Any ideas?
Thanks.

Please show the complete output of these two commands:
which warndlg -all
which msgbox -all
For warndlg
C:\Program Files\MATLAB\R2021a\toolbox\matlab\uitools\warndlg.m
For msgbox
C:\Program Files\MATLAB\R2021a\toolbox\matlab\uitools\msgbox.m
These functions do OS API calls, so might something have broken there?
I have no idea what OS API calls are! How do I test?
I just exited MATLAB and started up again, and it's working again, so I guess that the OS API (?) was indeed broken!
Thanks.
The operating system (OS, so Windows, MacOS, Ubuntu, Arch, etc) provides an application program interface (API) to do things like determining what files are in a folder etc. One of the things the OS can do is make a window. That is why the documentation warns that the windows may look differently between operating systems.
Thanks Rik. Your comment was a good clue to just restart MATLAB.
