I got this one at regular 1 v 1 mugen
other one just crashed and closed on its own showed nothing in 4 v 4 (tried 3 v 3 with characters I knew there were no errors never and still got crash)
I now tried same with 3 v 3 and still crashed and closed on its own

I had (Anime Super Battle Stars MUGEN) from 2016 or 17 I don't remember and updated and changed to the new screepack the Legacy one but still I'm getting all that errors and crashes
is there any way to fix all this error for once and for all?
