Hi,

I had a similar issue with Matlab 2018a (Access violation, Abnormal termination).

I contacted the support and got the following message:

"...you are running into a crash when MATLAB is trying to copy data from the managed .NET world to native MATLAB datatypes. And there is indeed an issue with this operation in MATLAB: during this operation the .NET data has to be "pinned" such that the .NET Garbage collector cannot delete or move the data while we are copying it. And while we actually intended to do that, we are in practice accidentally only preventing the garbage collector from deleting the data, not from moving it. So, a crash can occur if the .NET Garbage collector decides to move the data while we are copying from it. Typically, the garbage collector does not move around data that often, which explains why the issue does not always occur.

There are no workarounds in current MATLAB releases, there is simply no way in which we guarantee that the garbage collector will not move the data when the arrays have not been properly pinned.

This issue should be fixed in the upcoming R2020a release, in that version the arrays are pinned correctly."

There is already a Matlab 2020 pre-release version available.

Give a try!

Regards,

Felix
