File unexpected stopped working

I am also having issues after today's update. I can open files - but the program is does not work as expected - sometimes the audio won't play in the timeline. I can see the little > but nothing happens when I click on it.  I have to close and reopen the software to make it clickable (but twice I've had to reboot before it came back). When right-clicking something on my timeline, sometimes I have the option to click on "timing" and sometimes it's missing. I've run into a few more issues but those are the one's that come to mind now.
