Image not recorded on recording powerpoint presentation to local machine

[MO_TD]

I'm using Zoom 64-bit Windows client to deliver online lectures which are usually combination of talk, shared powerpoint presentation and videoclips. In the course of the lecture, I use New Share green button to toggle between my presentation and Windows media player (several times forth and back). Lecture is being recorded to the local machine. On today's lecture, the slides (video part of the presentation) was not recorded after the first toggle from media player to powerpoint (black screen), while sound (me talking to the mic) was recorded, as well as all videoclips. A week ago I was doing the same, but recorded my lecture to the cloud, and it went normal (except the resolution was lower than expected).  I wonder how this issue of local recording can be fixed? I did many times with previous versions of zoom, and never had this issue.
