When training a RL agent, after about 2000 episodes I get the following error and training doesn't continue:
render process terminated: null
java.lang.NoSuchFieldError: TS_PROCESS_OOM
I tried increasing the java heap memory to max but it doesn't work.
Any other suggestions would be greatly appreciated.

I get the same error, and I'm not even running anything! I'll be just viewing the source code of an m-file in the editor and MATLAB just kind of dies on me. I get the white editor (which cannot be recovered until I restart MATLAB) and the same error prints in my command window:
render process terminated: null
java.lang.NoSuchFieldError: TS_PROCESS_OOM
I have ample memory on my system and have about 50% of my memory free when this crash occurs, so I do not think it's actually a system memory issue. I think this is MATLAB internally mismanaging resources (at least for my flavor of this bug). Note that this occurs in the R2023a pre-release, and I had never experienced this bug on any previous version.
