Now send this log-file to Mathworks support (together with a short description of the problem you encounter):

Here i what AI tells you could try:

MATLAB 2023b crashing while editing a script is often related to Java-based UI issues (especially on macOS), graphics driver issues, or temporary file corruption. Here are the steps to recover your work and resolve the issue based on common experiences with R2023b.

1. Recover Unsaved Script

If you had an unsaved or "untitled" script open:

• Check Temp Folder: Type tempdir in the MATLAB command window (or check the temp folder path in your OS) to find where MATLAB stores backup files.
• Auto-Save Recovery: When restarting, MATLAB often offers a recovery session if it detects improper closure.
• File History: Check the matlab directory in your user profile for potential auto-save files.

2. Immediate Fixes & Workarounds

• Disable Data Tips (Variable Previews): A known issue in R2023a/b is that hovering over variables to see previews (datatips) while editing can cause crashes. Disable this in Preferences if necessary.
• Avoid Closing Plots Manually (macOS): On macOS (especially Sonoma), closing figures using the red 'X' can crash the editor. Use close all in the command window instead.
• Clear MATLAB Cache: Delete the ~/.matlab folder (or prefdir on Windows) to clear corrupted preferences, though this will reset settings.
• Run as Administrator (Windows): Occasionally, permissions issues cause editor crashes.

3. Stability Upgrades

• Update to Latest Update Version: Ensure you are running the latest update of 2023b (e.g., Update 5 or later) as many crashes were resolved in subsequent updates.
• Use the New Desktop (Beta): If you are on macOS and experiencing constant unresponsiveness, enable the new MATLAB desktop (available as a beta in recent R2023b updates) to bypass old Java issues.

4. If Crashes Persist

• Check Graphics Drivers: Update your system's graphics drivers, as the MATLAB editor relies on them heavily.
• Check for Infinite Loops: If the crash happens specifically when running code, ensure there are no infinite recursion/loops that exhaust system memory.
• Gather Diagnostics: Look for a matlab_crash_dump.* file in your temp directory and send it to MathWorks support.
