Lost access to the dlc even though I have the season pass

I was farming one of the bosses in the new dlc 4 and my pc crashed. When I restarted it told me that I had no access to any of the dlc’s, even though I had bought the super deluxe edition and all of the dlc’s were still downloaded. I’ve tried uninstalling the dlc’s and reinstalling them and it didn’t work. Same with uninstalling the game and the dlc’s and even reinstalling he whole epic games launcher did nothing. I need help
