What means error "Changes to this form will not be saved. 1 field does not meet its constraints."

I just updated to Qgis 3.20. Now I can no longer do multiple updates, due to a constraint at the field ID. I changed the constraint of ID but the problem stays.

I do can make changes when I select objects in the map.
