Using Queue item a second time with multichannel audio results in a crash on v20 Nexus which is a regression from v19 Matrix where this operation succeeds.

Kodi logs show browsing for a folder of multichannel files, using Queue item and successful play, then while the first file continues to play, browsing for a different folder multichannel files of same type and using Queue item on those. 

File types are FLAC, E-AC-3 JOC (Atmos) .m4a and Dolby TrueHD (Atmos) .mka

FYI looks like the devs were able to quickly ID where this bug was introduced and have a plan to squash it, kudos to them!
