I receive the following error when trying to lot using the MATLAB engine and Julia 1.10:

[31763] signal (11.1): Segmentation fault
in expression starting at /home/dkuettel/Documents/cr3bp/LowThrustOpt/testing/CRTBP_Multishoot_indirect_demo.jl:138
Allocations: 18782664 (Pool: 18765867; Big: 16797); GC: 27
Segmentation fault (core dumped)

My matlab code essentially looks like

mat"""
plot($x, $y)
"""

I am using :
-Linux Ubuntu 18.04.2 LTS (Bionic Beaver)
-Julia Version 1.9.0 (Julia version managed with Jill)
-MATLAB.jl v0.8.4 (https://github.com/JuliaInterop/MATLAB.jl/blob/master/README.md)
-MATLAB version R2023b

Everything works fine with Julia version 1.9

This error does not persist when using MATLAB version R2021a and Julia 1.10.

Any thoughts on why this is happening or what it takes to fix it? I don't have enough disk space for multiple versions of MATLAB and I think I need the latest versions. What can I do to help?

We need way more debugging information in order to make progress here. Starting with an empty environment, what are the minimal steps to reproduce?

If MATLAB.jl alone is in the environment, do you still have the problem? If other packages have to be loaded to have the problem, what are they?

If you can run a debugger, please do.

If you have a longer stack trace, please provide the entire thing.

Same issue here as well, in Windows 10, Julia 1.10 and Matlab R2020b. As soon as I load only the Matlab.jl and run MSession(), the Matlab command line window open and then Julia gives the error: ERROR: MATLAB.MEngineError("failed to open MATLAB engine session"). It was working on Julia 1.09 on my machine.
