    Hi.

    We've been experiencing a crash that appears on loading a new level. It is not 100%, but after some amount of loading it occurs (it could be 1 load, could be 5).

    Looks like it somehow related to the particle systems every time.

    In the .log file it simply outputs:
    But sometimes it writes a stacktrace. Sometimes we can take a stacktrace from the crashdump file. Here are 3 different stacktraces, but all they have in common this line:
    Here are some crash stacktraces:

    PS: Our temporary solution is -- we're disabling all particles on all scenes and enable them manually after the scene is loaded. Magically, that solves the crashes.

    Are you able to submit a bug report, with a reproduction project?
    We've not seen any other reports of this (yet)

    No, sorry. That happens on our very big project and stripping it down to a minimal reproduction project will be too much work.

    Also, the bug still reproduces on 2022.2.5, but with less chance (or we need to reload a level more times to get the crash). But it is still there, so that's not something new for ver .10
