When I use MATLAB's export image feature, I name the file "untietled" and all other names, MATLAB crashes and automatically quits

For other names the image export works ?

Do you have code you could include here to reproduce your problem ?

I'd contact MATLAB Support:

Well, I want to say you spelled untitled wrong, and that causes the problem. I know. You want a serious response.

I would first try to track things down. First, verify you can save an m-file using the editor, into that same directory. If you cannot do so, then you are a step closer to finding the problem.

Can you save a .mat file with some data in it into that directory?

Can you export an image (maybe a smaller one) as a a jpg file, using imwrite?

Next, how much disk space do you have? Is it enough to save a large image file? If not, then you have identified your problem.

Next, ask questions like do you have write access to the directory you want to save to? Do not try to save files into the MATLAB directories!

The point is, you need to try to nibble away at what is causing your problem. Eventually you will narrow it down, and then maybe you can get a better answer than what I've said.

Hello people from afar, for example, I created a two-dimensional scatter plot, when using the function of saving as as a suffix with .jpg/.png in the image window, I can only export the image with the name "untitled", if I change the file name and then click save, MATLAB will automatically crash and exit, although I can let him save as the name "untitled", and then exit MATLAB to modify the file name, but this is too troublesome...

If I could, I would like to send a screen recording video to show how this error occurred，what is your email?

[Torsten]

What's your command to save the image under the name "untitled" ?

If you look at the crash log file, do you see a reference to graphics_context.dll in it? If so, try updating to release R2023a Update 6 or later to see if this is bug report 3084267.

If the crash log file doesn't include that term, or you're using Update 6 or later already, please send the crash log file to Technical Support.

您好，我不确定在哪里查看崩溃日志？向GPT求助，却找不到
