Full VS Dump. I don’t see any symbols anywhere, so callstack is unreadable, but attaching it just in case.

Fmod crashes whole aplication silently and somehow bypasses our crash handler so it didn’t get registered until users started to complain. Is there a way to handle or supress Fmod crashes, to make them report an error instead of crashing whole application?

Edit: fixed logs and dump file, they are now from 20205 instead of 20107

I have reproduced this issue using that URL- it isn’t a valid m3u file, but other invalid m3u files are being handled without issue so I’m not sure what’s special about this one. I have passed this onto the dev team to look into, in the meantime I think the best thing to do for now would be to blacklist that URL from your application while we have a closer look at what’s going on here.
