Beta 23.1.0 Build 23 force quits on playback of MXF files (Windows)

Following on from my previous post, which I couldn't reply to for some reason, the behvaiour of the beta has now changed for me from high CPU to the app force quitting and disappearing off the screen without warning on playback of MXF files AVC codec, in this case 8bit 4:2:0 from FS5 if that helps. I don't need access to the Beta, I'm only posting this to aid with the eventual release of v23
