Why does the program freeze?

Question

NoSQL

Good afternoon!
Please help me figure it out. By pressing the button in Mongo, an element should be added to the document field ... The button goes out, but does not become available back and the whole form hangs, although the element was added to the database (checked through the Mongo console). What am I doing wrong?

private async Task AddReplic(string mess, string str)
        {
            var client1 = new MongoClient(connectionString);
            var database1 = client1.GetDatabase("test");
            var collection1 = database1.GetCollection<BsonDocument>("testcollection");
            var filter = Builders<BsonDocument>.Filter.Eq("Mess", mess);
            var update = Builders<BsonDocument>.Update.AddToSet("Replics",str);
            var result = await collection1.UpdateOneAsync(filter, update);
        }

        private void button2_Click(object sender, EventArgs e)
        {
            button2.Enabled = false;
            AddReplic("ТекстТекст","УраУра").GetAwaiter().GetResult();
            button2.Enabled = true;
        }

Add async to the click method definition and await when the method is called. From a mobile phone it’s hard to see what’s in add, the dependency can still be if there is a block before the first await
