[Matlab Online] Internal Error: "Reference to a cleared variable logger."

I am running a a long-ish script I have received from a colleague in Matlab Online. After running for some time (half an hour to a few hours) I receive the "Reference to a cleared variable logger." error, which according to the stacktrace originates in either mls.internal.figureCreated or internal.matlab.desktop.editor.ClearAndSetBreakpointsForFile (line 45)

Unfortunately, as soon as the error hits a popup tells me "Matlab has experienced an internal error and needs to be restarted". If I close the popup the page instantly refreshes and I lose the stacktrace etcetera. I managed to get the following printscreen of a partly visible stacktrace:

The script contains intermediate calls to clear variables but I would expect that not to interfere with matlab internals. Any help to resolve this issue would be greatly appreciated.

@MathWorks Support Team I am starting to suspect that this is a bug in Matlab Online. If I run the command scriptname I get a timeout warning after some time for 'being idle' (IE waiting for the script to finish). If I run the command run <scriptname.m> I do not get a timeout warning, and instead it seems my session gets partly killed on the background for being idle, tripping an error when my code tries to progress.
