On 1 June 2021, Dibusz was included in the final 26-man squad to represent Hungary at the rescheduled UEFA Euro 2020 tournament,[16] again serving as back-up, this time to Gulácsi who had inherited the number 1 jersey from the retired Király.[17]
Gulácsi's cruciate ligament injury in October 2022 saw Dibusz take his place in the Hungarian goal for the UEFA Euro 2024 qualifying campaign, with the Magyars going unbeaten throughout 2023.[18] He played eight matches during the Euro 2024 qualifiers, conceding seven goals and keeping three clean sheets.[19]
On 14 May 2024, Dibusz was named in Hungary's squad for UEFA Euro 2024.[20] However, he was an unused substitute in all three Group A matches as Gulácsi regained his place as starting goalkeeper.[21] In an interview with Nemzeti Sport, he said that he had come home disappointed from the Euro 2024.[22]
