I apologise if this has been written about elsewhere, but searching the forums and google haven't yielded anything helpful.
TL;DR: After upgrading the node-red install on my pi using the official script, everything appears to restart without error, but when I enter my credentials for the webUI, it cycles through some activities and progress bars, then gets stuck at "Adding flows to workspace" (about 90% through the progress bar).
It's been stuck there for about an hour. Restarting the pi and the node-red haven't helped.
It appears that nodes are active and operating in the background, as I get an instant message from a node which triggers on-load. I just can't access the UI.
Running node-red-log gives no errors, even on trace level, and sits quietly waiting:

My previous install of node-red had been via apt, but after upgrading from Stretch to Buster, I used the official node-red Pi install script. It completed without error, showing that it uninstalled the previous version and successfully installed the new one.
I am using projects, if that makes any difference?
Any help about where to look would be appreciated.
