when I load Photoshop, it locks up and does not respond to anything. have to use Task Manager to close, I have all the newest updates the version is V27.91. not sure what to do

Did previous versions run OK?

What plugins do you use? Are the same plugins installed for both the release and Beta versions?

Try starting Photoshop while holding down the Shift key.  This forces Photoshop to open but ignores all installed plugins, extensions etc.

Open the Beta version and go Help > System Info > Copy and paste to this thread.  This will tell us what we are dealing with.
