Hi,
I'm running MATLAB R2021b on CentOS. Output of hostnamectlis:
Operating System: CentOS Linux 7 (Core)
CPE OS Name: cpe:/o:centos:centos:7
Kernel: Linux 3.10.0-1160.el7.x86_64
Architecture: x86-64
I'm using MATLAB to run the Statistical Parametric Mapping toolbox, SPM12, which makes heavy use of MATLAB's GUI functions. When clicking on one of the buttons in the GUI, the GUI doesn't update as expected and I get the following errors:

What does this error mean? I am aware of a couple of threads on Mathworks that mention the error Exception in thread "AWT-EventQueue-0" but none of them mention the error java.lang.AbstractMethodError, which follows it.
What is the meaning of all this?
Cheers,
Michael

I have tried different MATLAB versions now. In R2020b, the GUI button likewise does not respond as expected. It does not throw an error in the Command Window. In R2019b, the GUI does respond as expected. So the error is not reproducible in R2019b. I will keep using this MATLAB version for now.
