--- Comment #1 from Jonathan Marten <jjm at keelhaul.me.uk> ---
This is not a KDE or Plasma problem.  If an NFS server is disconnected or shut
down while a client has mounted any of its filesystems, any access to that
filesystem will slow down or, in the worst case, hang indefinitely.  What
precisely happens depends on the server's export options and the client's mount
options, but the default in your case is 'hard' which means that access will be
retried indefinitely.  Dolphin or any other application which needs to access
the NFS filesystem can do nothing in this case.

Using the 'soft' mount option will give up eventually, but there is the
possibility of data corruption.

The only way to recover, if you are able to get to a root shell, is to forcibly
unmount any NFS filesystems.
