Premiere v24.0 Build 58 Export problems (using Productions)

1.  PP v24 Build 58

2. macOS 13.6, M1 Mac Studio, LucidLink as media drive.

3.  I'm working on a Productions project with media on LucidLink.   All was well for a week, but now we are having a number of problems with exports, on multiple stations, both PC and Mac.

File > Export Media via keyboard or by switching manually to the Export window works very rarely now and all exports need to be sent to AME.   Sometimes, PP will eventually switch to the Export tab, but the window will be completely blank.   Sometimes, the workspace looks completely strange.   Sometimes, the window looks right, but it's impossible to choose or change any options.   Sometimes, you can set off an export,  it seems to be exporting (to 'High Quality 1080p' preset) and the progress bar shows, but there is no export at the targeted directory.

Exporting through AME is working OK, thankfully.
