Library Search intermittent

I’m having an issue with Dynamo Library Search not responding to any inputs, whether in the sidebar search or the right-click quick search. In fact, with the quick search the word “Search” ghosts over what I’ve typed.

This of course makes Dynamo completely unusable, any suggestions?
Restarting Dynamo/Revit doesn’t solve the matter.

what version of revit/Dynamo is this?

Do you have two instances of Dynamo open? I ran into this issue when i had two instances of revit open and two instances of Dynamo.

Revit 2024.2, Dynamo 2.19

I had 2 instances of Revit open, but only one instance of Dynamo.
By closing all instances of Revit and trying again, it is working now, but I come across this issue fairly frequently

Do you frequently open multiple instances?

Often, yes. Working on a couple of live projects, along with developing the practice’s revised templates.

Yeah - I don’t know if that is fully supported. When I was in support this was one of those grey areas where most things work but some things (perhaps including Dynamo’s search) fail.
