Having issues with the plugins

This has been handled in other threads already.

The issue seems to mostly happen with Lightroom Classic 13.5 and macOS 14.6.1.
I solved this issue on my Mac by replacing LrC 13.5 by LrC 13.4

In CC go to your apps and click on the “…” do download and install version 13.4

Note: Before you downgrade, let Time Machine (or your favourite backup tool) do a backup.
