Recover Live Editor Code?

I loaded a trial version of Matlab and after a few hours of training I was editing code in the Live Editor. I was running the code which involved computing an array of 1000x240 elements. I was running slowly and displaying lots of what appear to be correct results. It seems to update the display after every element! After several minutes everything disappeared. I don't want to start over. Is there a file where Matlab has been saving the status of the Live Editor that I may be able to recover?

I did see the following error message in the Command Window. I think it says it ran out of memory. My Windows 64 machine has 64GB of memory.

render process terminated: null

java.lang.NoSuchFieldError: TS_PROCESS_OOM

Preferences -> General -> Java Heap Memory might have helped with Java running out of memory. (Note: you need to restart MATLAB after changing that preference.)

Walter, Thanks for your reply. I searched for an auto-save file, but could not find anything. I am not sure why auto-save was not saving anything since it took a few hours to write all the code.

I am also concerned that Matlab will crash rather than slow down because of memory. Sounds bizarre, especially on a machine with 64GB of memory and many TB of virtual memory. Something's wrong.

I am doing a trial so I will need to consider whether issues like this are a problem or not. So far, not so good.

TS_PROCESS_OOM appears to be associated With Chromium Embedded Framework (3), CEF3, and is generated when a process is killed due to be Out Of Memory.

However, it is not clear to me what relationship Chromium would have to LiveScript .

If you had happened to use something built with the newer uifigure instead of the older "traditional" figures, then I could see the potential for Chromium to be involved.

i found same problem which shows java.lang.NoSuchFieldError: TS_PROCESS_OOM. However, my machine is set 16G (Java Heap Memory) as Walter's suggestion. It is still not working. Is their any other suggestions for me?

[Jinqi Liu]

Hi David, have you solved this problem? I think I also encountered a similar problem. The above error still occurs after enlarge the java memory.

I have the same problem and I don't have the folder in Temp :/ Anyone can help please ?

I'm having this same problem. I have ample memory every time it crashes, with MATLAB consuming no where near my limits.

It crashes on me when I'm not even running anything; I'll just be scrolling through a file and bam, all-white editor with the following printed in the command window:

render process terminated: null

java.lang.NoSuchFieldError: TS_PROCESS_OOM

At this point, I'm forced to restart MATLAB to continue working. This seems to happen 1-3 times per day, and my memory usage for the whole computer never exceeds 50% of my available memory. So, it's not a memory limitation on the system (but it could be that MATLAB is doing a poor job using the available memory).

@Nick Patterson

You need to report that to Mathworks Support.

@Nick Patterson same, running R2023a. I have my MATLAB java heap set to 7988 MB (the max it'll let me set it to). System RAM is currently 64 GB, but I've got another 64 MB I'll soon install for 128 GB. I get this error frequently

render preocess terminated: null

java.lang.NoSuchFieldError: TS_PROCESS_OOM

when working with Live Scrips, which is pretty much always now. Any fixes out there??

The .mlx files have become increasingly buggier run-to-run; so much so that I'm considering going back to .m files. I do like the visual interface of the .mlx though so I'm trying my best to make it work. Just like you, I just hit it scrolling through the live script, not even running it (but I get it running it too). Plots also seem to pop out sometims but not other times, but that's for a separate thread.

Its too late, but I found a simple solution that could helped others:
