Can't add nodes using context menu

[1R1DDLE1]

Each time I press RMB in the editor, the list of available nodes is reloaded ( indexing?). Each time it takes several seconds.

Attention to the blue bar at the bottom of the menu

After initialization the input field for search does not work. I just can’t write there. No letters, no numbers - nothing. However, it is possible to select from the list of categories and add a node.

The search only works when pulling from another node.

Similar problem with other fields that have a search field. For example “General - Region & Language”

Example 'General - Language'

It is impossible to write text or paste (ctrl-c, ctrl-v) into such search fields.
