I am on version 2025.06.11.0058, but only because I upgraded from the stable release trying to resolve this issue.
I cannot seem to delete multiple channel collections. I even removed all of the channels from within them (so they are now empty) and still cannot delete the collections themselves. I am not seeing any references to an issue in the log either.
