P: Spacebar does not start playing the timeline

Exactly same here; the latest update is unusable

I am sorry; it`s been a heavy day 🙂 

I am on a MacBookPro, Ventura and actually (since this morning) use the latest version of PP

It is like the User "outward spiral" (please scroll down a little) mentions, but he is on windows ...

Yesterday everything was fine and smooth; today PP is unusable

The inspector does not function as well

The play button doesn't play footage and neither does the space button

Just downloaded and began using PrPro Beta 25.2.0 build 47 on Mac Studio M2 Max chip running Sequoia 15.1.1. When viewing clips in eithere the source window or program window, the space bar will start and stop the playhead; however, once I manually advance the playhead with the mouse, I can no longer get the playhead to start or stop with the space bar.  This does not happen with the regular program (25.1.0 Build 73) which I also have installed

With the new beta version, for some reason when I move the playhead, the play button / space bar no longer works. It shows it should be playing, but no time advances.

Same thing when bringing up the preview area, play button shows it should be playing, but that isn't happening.

Steps to reproduce:
    1. ... To recommence play on either the preview or primary Edit panel I need to run the opposite playhead and then immediately click the playhead I want to use and vice versa or neither will recommence after stopping the playhead, without restarting the program.
 
Result: ...
Expected: ...
 
System info
    Application: Premiere Pro (Beta) v25.2.0.46
    OS: Windows v10.0.19045, RAM: 31.91 GB GB, CPUs (logical): 16

Immediately after opening a project, playback in the sequence or program monitor panels will work until I attempt any editing task or even relocating the play head - from there on, the play head no longer responds to tapping the spacebar or clicking the play button, even though the play button indicates that it's in playback mode by changing to a stop button.

However, relocating the play head does refresh the current frame, and dragging the play head or shuttling with the left/right arrow keys does scrub through the footage, which makes me think that the "play" command is being ignored, rather than some graphics driver failure. 

The only way I can temporarily regain normal playback is by playing a clip in the source monitor, then switching back to the sequence or program monitor. But as soon as I attempt anything from there, the play head  freezes again.

[ UPDATE ] - No change in Build 47
