I've uploaded the dump (xmplay.exe_200427_183016.dmp), the top stack frame points at xmp-opus.dll. Before crashing, XMPlay itself also says: "The "Opus and WebM (rev.7)" plugin crashed while attempting to scan the following file:"
The crash happens while scanning the file. The first time I ran procdump, XMPlay didn't crash for some reason, and then subsequent attempts at playing the file also didn't crash (even without procdump attached).
