After encountering the similar problem and ending up in here (google search), i have tried ‘fix’ proposals through this discussion thread and those didn’t help at all, so now i believe i have found a ‘fix’ for this play button glitch:

Right click on the video footage in your source monitor window and then click ‘Clear in and out’:
magically, the play button starts working again … (for me at least)

You may have to repeat the same steps as many times as needed. This playback button issue appeared here with no reason when i was working on cutting out rushes into sub-clips as usual in preparation of a library of clips for a music video I’m making.

also, it is amazing to see popping up this kind of workflow-ruining bug which affects such a crucial workflow feature in such an advanced high-end software like this one …
