Pro Tools 11.3.1 Not Able To Load A Session.

Running Pro Tools 11.3.1 on a MacBook Pro with OS 11.9.5. Pro Tools will open but not load a session. The first error message is: Could not complete the Playback Engine command because Assertion in "/Volumes/Development/151228/ProTools/DFW/MacBuild/../Views/UMenu.MacOS.mm", line 1549.When I try to change the audio engine from the Setup menu I get: The current playback engine does not support a sample rate of 0 kHz,I had been running problem free for months, maybe years, using Mac 11.9.4 and PT 11.1. Then Pro Tools starting creating screen problems (a million lines) and then the playback engine error. I upgraded the OS and PT but still have the playback engine issue.
