    That's going to be difficult to diagnose from a Forum discussion. I suggest you click the Support button at the top of the screen and submit a ticket to get someone who can work directly with you on this problem.

    It's a time 0 simulation crash. You would hope there would be some clues to what caused it but it is pointing to external code in an unavailable function name.

    You can try running with a different version but I'm just shooting in the dark.

    Hi Tarique,

    I am having the same problem, and I was wondering if you have found the solution?

    I see the same issue, looks like it is related to XLM version and RHEL8 Linux versions. Better to deal with an AE directly.
