Can i get norway visa on short travel dates even with previous refusal last year?

Last year in November and December i was refused a Schengen visa from Iceland and Poland both reasons being no confirmed itinerary and Poland being no sure if i will come back. So I have a girlfriend from Norway (norway citizen) been together since 2 years traveled ti 3-4 countries together also and now i am planning to visit Norway and I have got the digital sponsorship form and invite form from 29th july to 24 September. But today is 15th july and I am afraid if i apply now it will be refused because being on a short notice. Wr have a music festival ticket also on 31july to 3august and my main purpose is to go and spend time with her and zher family and after that she will be coming back also to meet my family also in November. What do you suggest if i should apply with 29th July dates or cancel the hope of going to the music festival? I have

1. 2 years of itr
2. Well written sop with reason for refusal and why it happened and what changed
3. 10-11 lakhs in savings account.
4. Digital Sponsorship form from her side for the dates 25 july to 25 September directly submitted from UDI website to embassy.
5. Itenary with well organized things and laid out plans.
6. I can also het confirm both ways flight tickets and her tickets that she is also planning to visit india to meet my family.
7. Both the travel stamps together. And some photos and chats to provide as a dossier for legut relationship.
