Audio & Video out of sync

Downloaded the latest beta this morning (1/29/20), and trying to play any clips gives me a "Audio and Video clock out of sync in Adobe Player" error message. Audio plays back VERY choppy, and some audio doesn't play  back at all. I've tried ProRes, Mp4, XAVC-I,  and XDCAM EX footage.
