As soon as I launch matlab with ./matlab the window opens and I get this message. What can I do?
When I close the error window matlab stays open but I can't click on anything and it crashes a few seconds later.

This issue cropped up on me today; I was able to resolve it by blowing away (well ... moving, to be safe) my ~/.matlab/R2022a folder and letting MATLAB create a new one on startup. I'm not sure which file(s) caused the problem, but I just copied my history over to the newly created directory and that was good enough for me ...

Sadly, this doesn't work. It seems this is related to a jre upgrade on Ubuntu through apt. This method got matlab opened normally. However, as long as I open or create a new .m file, the same error occurs.

I have the exact same question after updateing to fedora 36 today. So I reinstalled matlab. This was a chore as I had to remove the libfreetype libraries to get it to work and then make sure root had access to the proper libraries. I got it reinstalled but it didn't solve the problem! What is going on?
