Why do I see 'Caught unexpected fl::except​::IInterna​lException​' no matter what command I put in?

I have been seeing this matlab error pop up no matter what input command I put in. I am on R2018b

It might have been a coincidence, but it generally happens when I put my laptop into sleep and log in again.

Here is an example of my command line:

>> clear

Caught unexpected fl::except::IInternalException

>> a = 1

Caught unexpected fl::except::IInternalException

>>close all

Caught unexpected fl::except::IInternalException

>>help

Caught unexpected fl::except::IInternalException

Possibly a graphics driver problem, especially on Ubuntu.

Thank you! These answers are definitely helpful, but I realized that my problem is slightly different with them since no matter what command I put in, even not graphic-related, I get this error.

I am working on windows 10 pro. Also, sometimes matlab just solves its own problem if I put the machine to sleep and log back in the next day.

Just curious, do you have a networked drive that you use? I see this problem sometimes too, and I wonder if it has something to do with commands failing due to a network disconnect.
