Ran into the same story.
And also
For some reason, in solving the problem, everywhere they suggest fixing the file
But in fact, you need to fix

<field
      name="cid"
      type="text"
      class="readonly"
      label="COM_JOOMGALLERY_CATMAN_CATEGORY_ID"
      size="20"
      readonly="true"
      disabled="true"
    />

replaced the line with

disabled="false"
