Problem Matlab/Java after system update

Hello everyone,

After updating the system, the editor in Matlab does not work. When trying to open it, a lot of Java error messages appear, which I list at the end. The Matlab version is 2023b, I use Java from the jre-openjdk package version 26.0.1. I tried older versions of Java, but they did not work either. I would be grateful for tips on how to solve the problem.
