ID safe UI hang with 22.9.0.71 NS update

One of my PCs (windows 10 x64) has received the 22.9.0.71 NS update.  Now going to Identity Safe via NS UI opens the Identity safe UI window , but it just says Loading.  Eventually windows says window not responding and kills it.  The safe can be opened via the firefox toolbar.

Going back to the previous version with NRnR all works again, until Liveupdate updates it to the new version again.  Is anyone else have this issue with the new NS update?
