Cause

• The 'Enable and disable editing from the Edit tab' check box is checked.

Solution or Workaround

Note:
Enable attachments on a feature class before associating attachments with a feature.

Uncheck the 'Enable and disable editing from the Edit tab' check box

Note:
Alternatively, on the top ribbon of the ArcGIS Pro project, click Project > Options > Editing. Navigate to the Session section and uncheck Enable and disable editing from the Edit tab.

Note:
Optionally, click Edit from the Manage Edits group on the Edit tab to start an edit session before adding the attachments.

Re-add the feature layers or restart ArcGIS Pro

Perform a clean uninstall and reinstall of ArcGIS Pro
