After upgrade to D10 on path
/node/add/claim?edit%5Brg_claim_entity_type_id%5D%5Bwidget%5D%5B0%5D%5Bvalue%5D=node&edit%5Brg_claim_node%5D%5Bwidget%5D%5B0%5D%5Btarget_id%5D=45098
(decoded: /node/add/claim?edit[rg_claim_entity_type_id][widget][0][value]=node&edit[rg_claim_node][widget][0][target_id]=45098)
I have:
