It's crashing in the video playback subsystem, which isn't part of Opus. It's probably a buggy video codec.
Is it possible to protect DOpus from these error?
Crash again when quit DOpus in DOpus 13.4.5 beta, already sent dump files. Thank you!
That crash in 13.4.5 was already fixed in 13.4.6. 
(Please start a new thread for new issues. These don't seem related to the script/crash the original post was about.)
