came back to computer and have black program and preview monitor, no audio, renderer greyed out

like i said, put my maxed out m1max down for a couple days and came back to an edit and have zero playback, no scrubbing no audio no messages nothing.   i can open a single video file but once i try and add the video to a current project it becomes black.      same issue when i start a new project and import the sequence im working on.         nothing had changed, i tried updating OSX, also moved to premiere 22.2.1 which didnt help.        any help would be appreciated
