Pls help

Hello, It seems I am dealing with a very unique issue in musescore studio. I haven't seen records of this on the forums and have talked to my music teachers and my private lessons instructor who has been using musescore for a very long time and no one has been able to help me. I make band shows and I have been working on one since february this year, I break up my movements into 5 different scores. I was very close to finally finishing the show, however whenever I tried opening the score, I am able to view the score well the soundfonts load, but whenever they finish, the score immediately crashes. There is no explanation for this glitch but, I cant open my score. Whenever I open musescore studio again, it gives me the option to restore the session, but whichever option I chose, the same crash occurs. It used to be where I have to sit there, painstakingly opening the score over and over again until it finally stays open, just for it to crash again after I input a few notes, however now I can't open the score at all. yesterday I sat at my computer for an hour opening the score over and over and over and nothing seems to work. I have asked just about everyone I know if they know how to fix this, but I have nothing. I can open every score except for the grand finale. I have reinstalled musescore, I have cleared my storage, I have done just about everything I can and nothing seems to work. There is no message saying that the file is corrupted or anything, it just wont open. Please help me.
