Matlab 2025 hangs itself whenever I try to plot a figure

I used MATLAB 2025b on a Windows 11 and whenever I try to plot a figure MATLAB hanged itself and I had to kill it in the task manager. Even a simple plot caused this. At first I suspected that my external monitor causes this because on that Simulink fonts are to big and when I move the Simulink window to the laptop monitor it is ok (on moving back it is to big again). It turned out that the problem is that starting MATLAB 2025a MATLAB does not use Java ( https://www.mathworks.com/matlabcentral/answers/2179665-how-can-i-enable-java-in-matlab-r2025a-and-newer ) and this is the problem (turning on Java did not help). My current workarround is that I moved back to MATLAB 2024b and now everything works fine. Does anybody have an idea how to fix this?

Thanks!
